Abstract
BACKGROUND Various treatment approaches for atrial fibrillation (AF) have demonstrated improved health status, yet the significance of these therapeutic interventions in individual patients remains unclear. OBJECTIVE This study aimed to evaluate health status changes in patients with early AF, focusing on those who experience clinically significant deterioration after treatment initiation. METHODS We analyzed data from a multicenter, prospective registry of newly diagnosed patients with AF. One-year changes in health status across different treatment strategies were assessed by the Atrial Fibrillation Effect on QualiTy-of-life Overall Summary (AFEQT-OS) score. Clinically relevant deterioration and improvement in health status were defined as ≥5-point decrease and increase in AFEQT-OS score, respectively; no change was -5 to 5 points. RESULTS Overall, 1960 patients with AF were evaluated. Mean AFEQT-OS scores at baseline and 1-year follow-up were 76.7 ± 17.7 and 85.4 ± 14.8, respectively. Although most patients (53.9%) experienced clinically important improvement, a considerable proportion had no change (28.7%) or deterioration (17.4%) in their health status. Proportions of patients with no change or deterioration varied by treatment strategy: 59.9%, 53.9%, and 32.0% in rate control, antiarrhythmic drug, and catheter ablation groups, respectively. The multivariable model identified older age, female sex, heart failure, coronary artery disease, and higher baseline AFEQT-OS score as independent predictors of worsening health status, regardless of treatment strategy. CONCLUSION Many patients with early AF experience worsening or no change in health status irrespective of treatment strategy. Standardizing patients' health status assessment, especially for patients with comorbidities, may aid in patients' selection and their outcomes.

Abstract
Importance A primary objective in managing atrial fibrillation (AF) is to optimize patients' health status, which can be done only if physicians accurately quantify the outcomes associated with AF in patients' lives. Objective To explore physicians' estimation of the health status of patients with AF and its association with subsequent care and outcomes. Design, Setting, and Participants A multicenter, prospective cohort study was conducted in 2 outpatient practices in Tokyo, Japan. Participants included patients with newly diagnosed AF or those referred for initial treatment of AF at outpatient practices and treating physicians from November 8, 2018, to April 1, 2020. Data analysis was performed from December 22, 2022, to July 7, 2023. Exposures Participating patients completed the Atrial Fibrillation Effect on Quality-of-Life (AFEQT) questionnaire, a 20-item tool covering 4 domains with a 7-point Likert scale; 3 domains (symptoms, daily activities, and treatment concerns) were used in this study. Blinded to patients' responses, treating physicians answered a 3-item questionnaire quantifying each patient's AFEQT domain with a single item. Patients' mean Likert scale responses within each AFEQT domain were subtracted from the physicians' assessments so that higher scores (≥0.5 points) indicate physician underestimation, while lower scores (≤0.5 points) indicate physician overestimation of the health status of patients with AF. Main Outcomes and Measures The independent association of physician-patient concordance with treatment escalation (alteration or initiation of antiarrhythmic drugs, cardioversion, or catheter ablation) and 1-year adjusted changes in AFEQT scores. Results Among 330 patients (238 [72.1%] men; mean [SD] age, 67.9 [11.9] years; 163 [49.4%] with paroxysmal AF), physicians correctly estimated health status in 112 patients (33.9%), underestimated it in 42 patients (12.7%), and overestimated it in 176 patients (53.3%). Treatment escalation occurred in 63.6% of patients whose health status was correctly estimated, 47.6% of those whose health status was underestimated, and 66.3% of patients whose health status was overestimated. After multivariable adjustment, underestimation of health status was independently associated with less treatment escalation (adjusted odds ratio, 0.43; 95% CI, 0.20-0.90) and less frequent AFEQT overall summary score improvement at 1 year (underestimated, 2.5 [95% CI, -1.6 to 6.7] vs correctly and overestimated health status, 8.4 [95% CI, 7.0-9.9] points; P = .01). Conclusions and Relevance In this cohort study, physician underestimation of the health status of patients with AF was common and associated with less aggressive treatment and less health status improvement at 1 year.

Abstract
BACKGROUND Catheter ablation (CA) benefits atrial fibrillation (AF) patients with heart failure (HF). Brain natriuretic peptide (BNP), a marker of left-ventricular pressure load, may serve as a potential surrogate for predicting quality of life (QOL) in a broader range of patients. METHODS Within the multicenter KiCS-AF registry, 491 AF patients underwent CA without clinical HF (e.g., documented history of HF, left ventricular ejection fraction ≤ 40%, or BNP levels ≥ 100 pg/mL). Participants, aged 61 ± 10 years, were categorized by baseline BNP quartiles. Atrial Fibrillation Effect on QualiTy-of-Life (AFEQT) questionnaire assessments were assessed at baseline and 1 year. RESULTS A lower baseline BNP correlated with reduced AFEQT scores. Post CA, all groups showed significant AFEQT score improvements. The lower-BNP group displayed notable enhancements (18.2 ± 1.2, 15.0 ± 1.1, 12.6 ± 1.2, 13.6 ± 1.2, p < 0.005), especially in symptom and treatment concern areas. Even those with normal BNP levels (≤18.4 pg/mL) exhibited significant QOL improvements. Comparing paroxysmal AF (PAF) and non-PAF groups, the PAF group, especially with higher BNP levels, showed greater AFEQT score improvements. CONCLUSIONS This study establishes BNP as a predictive marker for QOL enhancement in non-HF patients undergoing CA for AF. BNP levels represent AF stages, with individuals in earlier stages, especially within normal BNP levels, experiencing greater QOL improvements.

Abstract
AIMS The discontinuation of oral anticoagulants (OACs) remains as a significant concern in the management of atrial fibrillation (AF). The discontinuation rate may vary depending on management strategy, and physicians may also discontinue OACs due to concerns about patient satisfaction with their care. We aimed to assess the incidence of OAC discontinuation and its relationship to patients' health in an outpatient AF registry. METHODS AND RESULTS From a multicenter registry for newly recognized AF patients (n = 3313), we extracted 1647 (49.7%) patients with OACs and a CHA2DS2-Vasc score of ≥2. Discontinuation was defined as sustained cessation of OACs within a 1-year follow-up. We examined predictors associated with discontinuation and its relations to health status defined by the AFEQT questionnaire. Of the 1647 patients, 385 (23.6%) discontinued OACs after 1 year, with discontinuation rates varying across treatment strategies (15.3% for catheter ablation, 4.9% for rhythm control with antiarrhythmic drugs, and 3.0% for rate control). Successful rhythm control was associated with discontinuation in the catheter ablation (OR 6.61, 95% CI 3.00-14.6, p < 0.001) and antiarrhythmic drugs (OR 6.47, 95% CI 2.62-15.9, p < 0.001) groups, whereas the incidence of bleeding events within 1 year was associated with discontinuation in the rate control group. One-year AFEQT scores did not significantly differ between patients who discontinued OACs and those who did not in each treatment strategy group. CONCLUSIONS OAC discontinuation was common among AF patients with significant stroke risk but varied depending on the chosen treatment strategy. This study also found no significant association between OAC discontinuation and patients' health status.

Abstract
Background Catheter ablation (CA) for atrial fibrillation (AF) is preferred for paroxysmal AF (PAF) but selectively performed in patients with persistent AF (PersAF). This study aimed to investigate the prognostic differences and consequences of CA based on the AF type. Methods and Results Data from a multicenter AF cohort study were analyzed, categorizing patients as PAF or PersAF according to AF duration (≤7 or >7 days, respectively). A composite of all-cause death, heart failure hospitalization, stroke, and bleeding events during 2-year follow-up and changes in the Atrial Fibrillation Effect on Quality-of-life score were compared. Additionally, propensity score matching was performed to compare clinical outcomes of patients with and without CA in both AF types. Among 2788 patients, 51.6% and 48.4% had PAF and PersAF, respectively. Patients with PersAF had a higher incidence of the composite outcome (12.8% versus 7.2%; P<0.001) and smaller improvements in Atrial Fibrillation Effect on Quality-of-life scores than those with PAF. After adjusting for baseline characteristics, PersAF was an independent predictor of adverse outcomes (adjusted hazard ratio, 1.35 [95% CI, 1.30-1.78], P=0.031) and was associated with poor improvements in Atrial Fibrillation Effect on Quality-of-life scores. Propensity score matching analysis showed that the CA group had significantly fewer adverse events than the medication group among patients with PAF (odds ratio, 0.31 [95% CI, 0.18-0.68]; P=0.002). Patients with PersAF showed a similar but nonsignificant trend. Conclusions PersAF is a risk factor for worse clinical outcomes, including patients' health status. CA is associated with fewer adverse events, although careful consideration is required based on the AF type.

Abstract
AIMS The purpose of this study is to utilize PROs to determine the percentage of patients concerned about mild to moderate bleeding side effects of anticoagulants. METHODS AND RESULTS We consecutively enrolled 3,312 newly diagnosed or referred patients for atrial fibrillation (AF) management from 11 sites within the Keio interhospital Cardiovascular Studies-Atrial Fibrillation Registry between September 2012 and May 2018. Of these patients, 2,636 (79.5%) were taking oral anticoagulants at enrollment. Using the Atrial Fibrillation Effect on Quality-of-life questionnaire (AFEQT), the patients who responded "1: not at all bothered" or "2: hardly bothered" on the seven-point scale regarding bleeding side effects were classified as the "no OAC concern" group while those responding "3: a little bothered" to "7: extremely bothered" were classified as the "OAC concern" group. On baseline analysis, 29.3% (n = 772) were "concerned" about bleeding side effects. The proportion of women and patients with AF-related symptoms was higher in the OAC concern vs. no OAC concern group (36.9% vs. 29.8%, p < 0.0004 and 66.2% vs. 56.7%, p < 0.0001, respectively). The CHADS2 scores ≥ 2 were comparable between groups. Of the 430 patients in the 1-year follow-up analysis, the proportion of the continued OAC concern group (1 year from enrollment) was 41.6%.The dabigatran, rivaroxaban, and apixaban usage rates were comparable between the two groups in baseline and 1-year follow-up analysis. CONCLUSION Approximately one-third of all patients with AF on anticoagulant therapy were concerned regarding bleeding from short-and long-term anticoagulant use.

Abstract
BACKGROUND Clinical practice guidelines recommend optimizing the health status of patients with atrial fibrillation (AF) as a primary treatment goal. Whether disease-specific health status is associated with subsequent clinical events is unknown. OBJECTIVES The aim of this study was to investigate the association between health status and subsequent clinical events among patients with AF. METHODS Using a prospective cohort study of patients with new-onset AF referred to 11 hospitals (n = 3,313, 68.4% men, mean age 67.8 ± 11.6 years), data were extracted from 3,296 patients (99.4%) who completed the disease-specific Atrial Fibrillation Effects on Quality-of-Life (AFEQT) questionnaire between 2012 and 2018. Factors associated with baseline AFEQT overall summary (OS) score and associations between major adverse cardiovascular or neurologic events (MACNE; a composite of all-cause death, stroke, or new-onset heart failure hospitalization) over 2 years were investigated. RESULTS Overall, 517 participants (15.6%) had poor to fair health status (AFEQT OS <60), and 1,035 (31.2%) had fair to good health status (AFEQT OS 60 to <80) at baseline. Female sex, younger age, family history of AF, higher baseline heart rate, paroxysmal AF, initial visit to the emergency department, and history of heart failure were associated with lower AFEQT OS scores. Of those, 226 participants (6.8%) experienced MACNE; restricted cubic spline analysis with adjustment for factors associated with baseline AFEQT score showed a nonlinear increase in the risk for MACNE with AFEQT OS score <80. The strongest associations were observed for baseline AFEQT daily activity scores (for AFEQT daily activity score of <80 vs ≥80, HR: 1.65; 95% CI: 1.21-2.25). CONCLUSIONS Diminished health status in patients with AF is common and is independently associated with subsequent adverse cardiovascular events.

Abstract
AIMS Linear lesions are routinely created by radiofrequency catheter ablation. Unwanted electrical conduction gaps can be produced and are often difficult to ablate. This study aimed to clarify the characteristics of conduction gaps during atrial fibrillation ablation by analysing bidirectional activation maps using a high-density mapping system (RHYTHMIA). METHODS AND RESULTS This retrospective study included 31 patients who had conduction gaps along pulmonary vein (PV) isolation or box ablation lesions. Activation maps were sequentially created during pacing from the coronary sinus and PV to reveal the earliest activation site, defined by the entrance and exit. The locations, length between the entrance and exit (gap length), and direction were analysed. Thirty-four bidirectional activation maps were drawn: 21 were box isolation lesions (box group), and 13 were PV isolation lesions (PVI group). Among the box group, nine conduction gaps were present in the roof region and 12 in the bottom region, while nine in right PV and four in left PV among the PVI group. Gap lengths in the roof region were longer than those in the bottom region (26.8 ± 11.8 vs. 14.5 ± 9.8 mm; P = 0.022), while those in right PV tended to longer than those in left PV (28.0 ± 15.3 vs. 16.8 ± 8.0 mm, P = 0.201). CONCLUSION The entrances and exits of electrical conduction gaps were separated, especially in the roof region, indicating that epicardial conduction might contribute to gap formation. Identifying the bidirectional conduction gap might indicate the location and direction of epicardial conduction.

Abstract
AIMS The usefulness of catheter ablation (CA) for atrial fibrillation (AF) across a broad spectrum of heart failure (HF) patients remains to be established. We assessed the association of CA with both health-related quality of life (QoL) and cardiovascular events among HF patients with reduced and preserved left ventricular ejection fraction (LVEF) in an 'all-comer' outpatient-based AF registry. METHODS AND RESULTS Of 3303 patients with AF consecutively enrolled in a retrospective multicentre registry that mandated the Atrial Fibrillation Effect on QualiTy-of-life (AFEQT) questionnaire at registration and 1-year follow-up, we extracted data from 530 patients complicating clinical HF. The association between CA and both 1-year change in AFEQT Overall Summary (AFEQT-OS) scores and 2-year composite clinical outcomes (including all-cause death, stroke, and HF hospitalization) was assessed by multivariable analyses. The median duration of AF was 108 days (52-218 days), and 83.4% had LVEF >35%. Overall, 75 patients (14.2%) underwent CA for AF within 1-year after registration. At 1-year follow-up, 67.2% in the ablation group showed clinically meaningful improvements of ≥ 5 points in AFEQT-OS score than 47.8% in the non-ablation group {adjusted odds ratio, 2.03 [95% confidence interval (CI): 1.13-3.64], P = 0.017}. Furthermore, the composite endpoint of all-cause death, stroke, and HF hospitalization occurred less frequently in the ablation group than the non-ablation group [adjusted hazard ratio, 0.27 (95% CI: 0.09-0.86), P = 0.027]. CONCLUSION Among AF-HF patients, CA was associated with improved QoL and lower risk of cardiovascular events against drug therapy alone, even for patients with mildly reduced and preserved LVEF.

Abstract
BACKGROUND Recent randomized clinical trials have demonstrated that applying rhythm control during the early stage of atrial fibrillation (AF) may lead to improved clinical outcomes. However, the effects of this modality on health-related quality of life (HRQoL) have not been fully investigated. We aimed to assess the association between the AF stage, determined by the time between AF diagnosis and referral to the cardiology clinic, and HRQoL outcomes. METHODS Using an outpatients-based multicenter AF registry (n = 3,313), we analyzed 2,070 patients with AF diagnosed within 5 years. The patients were divided into 2 groups according to AF stage: early and late AF (AF duration ≤1 and >1 year, respectively). All patients had HRQoL information collected at baseline and 1 year after their initial treatment (assessed via the Atrial Fibrillation Effect on Quality-of-Life-overall summary [AFEQT-OS] score, with higher scores reflecting better HRQoL). The change in AFEQT-OS was adjusted for patient characteristics using a generalized linear mixed model. RESULTS The early AF group (n = 1,644) was older (early, 68.5 ± 11.1, late, 64.4 ± 10.6 years, P < .001) and had more heart failure (early, 19.9%, late, 12.7%, P < .001) than the late AF group (n = 426). At 1 year after treatment, the adjusted changes in AFEQT-OS were similar in patients with rhythm (adjusted difference [SE], early, 8.4 [1.2], late, 7.2 [1.4], P = .15) or rate (early, 4.0 [0.7], late, 2.3 [1.4], P = .16) control, regardless of AF stage. Furthermore, the improvement in HRQoL was similar between early and late AF in patients undergoing catheter ablation (early, 10.2 [2.1], late, 9.8 [2.4], P = .78), whereas a significant difference was observed in those receiving antiarrhythmic drug therapy alone (early, 10.2 [1.4], late, 3.5 [2.2], P < .001). CONCLUSIONS Rhythm control therapy provided clinically meaningful improvements in HRQoL, regardless of AF stage. For patients with impaired HRQoL, AF duration should not be a deterrent to treatment, especially catheter ablation.

Abstract
BACKGROUND Early detection of atrial fibrillation (AF) is important. Japan has a universal screening system, and regular health screening (HS) is available to support AF detection without a hospital visit. However, health-related outcomes and other characteristics of HS-detected and conventionally diagnosed AF remain unknown. HYPOTHESIS That the characteristics and health-related outcomes of patients with HS-detected AF may differ from those of patients whose AF was detected by other procedures. METHODS In total, 3318 consecutive newly referred AF cases were enrolled; demographic characteristics and health-related and clinical outcomes were compared between two groups created based on the mode of AF detection (the HS and non-HS groups). Health-related outcomes were assessed using the AF Effect on QualiTy-of-life (AFEQT) questionnaire at baseline and after 1 year of follow-up. RESULTS AF was detected by HS in 25.0% of patients; these patients had lower CHADS2 scores (1.01 vs. 1.50, p < .001), higher prevalence of persistent AF (odds ratio, 95% confidence interval; 2.21, 1.88-2.60) and asymptomatic presentation (3.19, 2.71-3.76), and better baseline QoL scores (83.6 vs. 75.0; p < .001). Catheter ablation was more frequently performed in the HS group at follow-up (44.4% vs. 34.1%; p < .001). At 1-year follow-up, the AFEQT scores of the HS group were significantly better in most subdomains. CONCLUSIONS In the Japanese registry, AF was detected via HS in 25% of patients referred to specialty centers for management. Notably, the overall health status of patients with HS-detected AF improved after medical interventions, including catheter ablations.

Abstract
Abstract
Introduction
The electrical pulmonary vein (PV) isolation has been established as a curative therapy for paroxysmal atrial fibrillation (AF). Arctic Front™cryoballoon has been used worldwide for AF cryoablation. Recently, a new cryoballoon, POLARxTM CRYOABLATION system have been introduced, of which material of the balloon is softer and the N2O gas flow rate is higher.
Purpose
The aim was to investigate the procedural parameter and efficacy of POLARx comparing with Arctic Front.
Methods
This retrospective single center study included 101 consecutive patients who underwent paroxysmal AF ablation using cryoballoon at Keio University hospital from April 2021 to March 2022. The procedural data including the cryoballoon temperature and the number and duration of cryoablation were compared between POLARx (POLARx group) and ARCTIC FRONT ADVANCE PRO (AFA group). After the cryoablation, we added the radiofrequency application in order to maximize the isolated area when the voltage was remained inside PV (Figure 1). The necessities of the additional radiofrequency applications were also compared.
Results
In the present study, 64 patients in AFA group and 37 patients in POLARx group were analyzed. POLARx group included younger population and less females (62.8±9.9 vs 67.5±9.4 year of age, P=0.02; 13.5 vs 32.8%, P=0.04). There was no significant difference in comorbidities and examination data such as left atrium diameter or brain natriuretic peptide level. The minimal cryoballoon temperatures reached in POLARx group were lower than AFA group (−59.3±6.2 vs −47.7±7.5°C, P<0.01). No difference was found in the total number and duration of cryoablation and the time to isolate PV (6.1±2.1 vs 5.9±1.6, P=0.69; 790.2±256.1 vs 776.1±235.0 sec, P=0.69; 41.8±21.3 vs 47.1±29.6 sec, P=0.44, respectively). With regard to individual PVs, the total number and duration were tended to be larger at right superior PV in POLARx group (1.9±1.1 vs 1.4±0.7, P=0.01; 231.8±123.8 vs 193.2±83.0 sec, P=0.07), while there was no significant difference at the other PVs. The rate of successful PV isolation by a single cryo-application was not different between AFA and POLARx group (54.3 vs 61.4%, P=0.17). The additional radiofrequency applications were more frequent in AFA group (14.8 vs. 4.9%, P=0.003). There was a significant difference at right inferior PV (32.8 vs 8.1%, P=0.01), while not at left superior PV, left inferior PV and right superior PV (9.4 vs 2.9%, P=0.42; 9.4 vs 5.7%, P=0.71; 7.8 vs 2.7%, P=0.41). Phrenic nerve injury was occurred 1 case in both group and esophageal ulcer was occurred in 1 case in AFA group. No other complication including cardiac tamponade was occurred.
Conclusion
The total number and duration of cryoablation were not significantly different between AFA and POLARx group, except for right superior PV. There was an advantage in largely isolating right inferior PV in POLARx group comparing with AFA group.

Abstract
The prevalence of atrial tachyarrhythmia is high in patients with atrial septal defect (ASD), and catheter ablation (CA) is often performed before percutaneous ASD closure. We aimed to clarify the effect of CA on the ASD size. We analysed 16 patients with secundum ASD who had a history of CA for atrial tachyarrhythmia and underwent ASD size evaluation before and after CA. The size of ASD significantly decreased after CA. Younger age and lower tricuspid regurgitation pressure gradients and pulmonary arterial systolic pressures were associated with size reduction. These factors are crucial for making strategies of percutaneous ASD closure.

Abstract
Background: Early identification of atrial fibrillation (AF) patients at risk for heart failure (HF) remains critical for improving their outcomes. We aimed to investigate whether indices of left ventricular diastolic dysfunction (LVDD) can stratify AF patients without clinical history of HF. Methods: We extracted 1775 patients’ data from a prospective cohort that consecutively recruited recently recognized AF patients with ejection fraction ≥50%. We categorized patients as LVDD grade 0 (none) to 3 (severe) based on mitral deceleration time and E/e’ per the American Society of Echocardiography recommendation. The primary outcome was a composite of all-cause death, stroke, and HF hospitalization during the 2-year follow-up. We also investigated the Atrial Fibrillation Effects on QualiTy-of-Life (AFEQT) scores. Results: Overall, 857 (48.3%) had mild or higher LVDD. Incidence of primary outcomes increased in parallel with LVDD grading (1.8%, 2.8%, 6.5%, and 8.1% for grades 0−3, respectively, p < 0.001), and the presence of grade 3 LVDD was an independent predictor of the primary outcome (adjusted HR 2.28 (vs. grade 0), 95%CI 1.13−4.60). Furthermore, patients with LVDD had lower AFEQT scores at the enrollment and 1-year follow-up. Conclusions: LVDD indices were associated with adverse clinical outcomes and patients’ perceived health status in a recently diagnosed AF cohort without HF.

Abstract
Patients with atrial fibrillation (AF) at the highest risk of progression to heart failure (HF) need to be identified. We investigated whether QRS duration can stratify patients with AF at risk for poor clinical outcomes, including health-related quality of life (HR-QoL). We analyzed data from a multicenter registry-based cohort study of patients with AF. Patients were grouped according to the QRS duration (narrow: <120 ms; wide: ≥120 ms) at registration (baseline). The primary outcome was a composite of all-cause death and HF hospitalizations during a 2-year follow-up. In addition, the AF effect on the quality-of-life overall summary score was compared between the groups. In 3,269 patients, 302 (9.2%) had a wide QRS; these patients were more likely to be older, male, and have higher CHA2DS2-VASc scores than those with a narrow QRS. The incidence of the composite outcome was higher in patients with a wide QRS than those with a narrow QRS (13.1% vs 4.9%, p <0.001). After adjustment, a wide QRS was an independent predictor of the primary outcome (adjusted hazard ratio 1.58, 95% confidence interval 1.09 to 2.29, p = 0.016), and the results persisted after the exclusion of patients with bundle branch block or cardiac implantable electronic devices. Regarding HR-QoL outcomes, patients with a wide QRS were less likely to improve AF effect on quality-of-life overall summary scores at 1 year than those with a narrow QRS (adjusted difference -2.31, 95% confidence interval -4.06 to -0.57, p = 0.009). QRS prolongation, even for a nonspecific conduction disturbance, was an independent predictor of adverse outcomes and worse HR-QoL in patients with AF.

Abstract
Background Atrial fibrillation and heart failure (HF) possess mutual risk factors and share a common pathophysiological pathway. Tricuspid regurgitation (TR) is a known predictor of adverse events in patients with HF. However, its implications on patients with atrial fibrillation in its early stage remain unknown. Methods and Results Data of 2211 patients without previous HF diagnosis were extracted from a prospective, multicenter registry of newly diagnosed patients with atrial fibrillation. TR was categorized as absent, mild, moderate, and severe based on the American Society of Echocardiography recommendations. The primary outcome was time to first hospitalization for HF after enrollment. The Atrial Fibrillation Effects on Quality‐of‐Life scores were compared. Overall, 1107 patients (50.1%) had TR (42.3%, 7.2%, and 0.6% for mild, moderate, and severe, respectively). During follow‐up (median 730 [interquartile range, 366–731] days), 44 patients (2.0%) experienced HF hospitalization, and the incidence increased with severity of TR (P<0.001). TR was an associated predictor of the primary outcome (hazard ratio [HR]: 2.51, P=0.050; HR: 6.19, P=0.008; for moderate and severe TR versus no TR). Changes in AFEQT overall score were negatively related to TR severity (8.7±17.5 versus 8.5±17.0 versus 3.1±17.5 versus 1.4±11.8, absent versus mild versus moderate versus severe TR, respectively), although it was not an independent predictor after adjustments. Conclusions TR severity at atrial fibrillation diagnosis was an associated predictor of subsequent hospitalization for HF, which may warrant the need for a more intensive follow‐up and HF‐related management.

Abstract
Sleep disorders and sleep duration have attracted considerable attention as potential modifiable risk factors for the development and progression of heart failure (HF). However, whether these sleep behaviors could aggravate the underlying cardiac condition remains ambiguous. We evaluated the associations between the levels of plasma B-type natriuretic peptide (BNP) and sleep-disordered breathing (SDB), sleep quality and quantity, or daytime sleepiness in cardiovascular diseases (CVD) patients. A total of 1717 consecutive patients with CVD [median age, 66 years (55-74 years); female, 27.5%] were enrolled. SDB was screened by nocturnal pulse oximetry; sleep quality and quantity were determined by Pittsburg Sleep Quality Index, and daytime sleepiness was examined by Epworth Sleepiness Scale. The median plasma BNP level was 54.9 pg/ml (23.5-146.4 pg/ml). Multiple regression analyses showed that the BNP level in the highest quintile (BNP > 181.8 pg/ml) was associated with SDB (severe: OR, 5.88; 95% CI 3.17-10.88; moderate: OR, 3.62; 95% CI 2.17-6.02; mild: OR, 2.22: 95% CI 1.42-3.47). There were no significant associations between other sleep parameters and higher BNP levels. The relationship between SDB and BNP levels was unchanged regardless of the previous history of symptomatic HF. SDB was independently associated with the elevated plasma BNP level in patients with a variety of CVD.

Abstract
The prognostic impact of anemia, especially mild anemia, in atrial fibrillation (AF) remains unclear. We examined clinical burdens of mild anemia on the quality of life (QoL) and clinical outcomes of 1,677 AF patients. Patients were divided into a non-anemia (hemoglobin [Hb] ≥13 g/dl for men and Hb ≥12 g/dl for women) and a mild anemia group (10≤ Hb <13 g/dl for men and 10≤ Hb <12 g/dl for women). At baseline, 22.5% of patients (n = 378) had anemia; patients in the mild anemia group had higher CHA2DS2-VASc scores (3.7 vs 2.7; p <0.01) and brain natriuretic peptide levels (253.5 vs 159.6 pg/ml; p <0.01) and were more likely to develop chronic kidney disease (64.2 vs 42.9%; p <0.01) than those in the non-anemia group. During follow-up (mean 1.7 ± 0.4 years), patients with mild anemia had a higher risk of heart failure hospitalization and major bleeding events than those without (12.2 vs 3.8%; p <0.01 and 5.6 vs 2.5%; p <0.01, respectively). Mild anemia was an independent risk factor for heart failure hospitalization (adjusted hazard ratio: 1.67, 95% confidence interval 1.06 to 2.62, p = 0.03) but not for major bleeding (adjusted hazard ratio: 1.44, 95% confidence interval 0.80 to 2.62, p = 0.23). QoL improvement was less likely in the mild anemia group during follow-up, despite the lack of significant differences at baseline. In conclusion, the presence of even mild anemia was associated with increased risks of heart failure hospitalization and poor QoL improvement.

Abstract
Background Randomized clinical trials have demonstrated that catheter ablation (CA) for atrial fibrillation improves health‐related quality of life (HRQoL). In daily practice, however, CA is performed on a wide range of patients, and outcomes may vary. We aimed to examine baseline and 1‐year HRQoL outcomes of patients with atrial fibrillation after CA in daily practice. Methods and Results Using a registry‐based cohort study designed to recruit patients with atrial fibrillation newly referred to 11 hospitals, we extracted data from 1097 consecutive patients with atrial fibrillation who underwent CA between 2012 and 2019. The Atrial Fibrillation Effects on Quality of Life Overall Summary (AFEQT‐OS) was assessed at registration and 1 year after, and a 5‐point increase in AFEQT‐OS score was considered a meaningful improvement. Overall, the median age was 64 (interquartile range, 56–70) years, 836 (76.2%) were men, and 93.0% (n=1021) of the patients answered the AFEQT questionnaire. The mean AFEQT‐OS score was 74.9 (SD, 18.0) at registration and 88.8 (SD, 12.6) at 1 year after. Notably, the incidence of meaningful improvement in HRQoL after CA was 88.6% for the patients with impaired HRQoL (AFEQT‐OS score <80), which was only 40.1% in those with preserved HRQoL (AFEQT‐OS score ≥80). Female sex, left atrium diameter, and high baseline HRQoL were independently associated with nonimprovement after CA. Conclusions The improvement in HRQoL after CA was similar to that seen in clinical trials; however, one‐third of patients did not show improvement. These results underscore the importance of quantitative evaluation of patients’ HRQoL to maximize the effect of CA before its performance.

Abstract
AIMS Frequent nightmares can pose a serious clinical problem, especially in association with sleep and psychological disturbances, in the general population. However, this association has not been investigated in inpatients with cardiovascular (CV) diseases. Furthermore, whether CV medications could induce iatrogenic nightmares remains unknown. In a cross-sectional designed study, we evaluated the prevalence and determinants of frequent nightmares and its association with sleep and psychological disturbances among hospitalized CV patients. METHODS AND RESULTS A total of 1233 patients (mean age, 64 ± 15 years; 25.1% female) hospitalized for various CV diseases in a single university hospital were enrolled. We assessed nightmares and sleep characteristics using the Pittsburgh Sleep Quality Index (PSQI), sleep-disordered breathing (SDB) using nocturnal pulse oximetry, and psychological disturbances using Hospital Anxiety and Depression Scale (HADS). Overall, 14.8% and 3.6% of the patients had at least one nightmare per month and per week (frequent nightmares), respectively. In this cohort, 45.9% had insomnia (modified PSQI > 5), 28.0% had SDB (3% oxygen desaturation index > 15), 18.5% had depression (HADS-depression ≥ 8), and 16.9% had anxiety (HADS-anxiety ≥ 8). Frequent nightmares were not associated with CV medications and SDB but were associated with depression [odds ratio (OR) = 4.61, 95% confidence interval (CI) = 2.03-10.48], anxiety (OR = 5.32, 95% CI = 2.36-12.01), and insomnia (OR = 7.15, 95% CI = 2.41-21.22). CONCLUSIONS Frequent nightmares were not uncommon in patients hospitalized for CV diseases. Although the cause-effect relationship is unclear, frequent nightmares were associated with psychological disturbances and insomnia, but not iatrogenic factors, among hospitalized CV patients. Cardiologists should be more conscientious to nightmare complaints with respect to screening for psychological disturbances and insomnia.

Abstract
BACKGROUND A novel measurement of the local impedance (LI) and electrograms recorded from micro-electrodes on catheter tip has been developed. However, the data during pulmonary vein (PV) ablation is not sufficient. We aimed to investigate the utility of this measurement during initial atrial fibrillation (AF) ablation. METHODS We investigated 111 representative radiofrequency applications in 7 AF patients without a history of prior ablation (6 males, age 68 [65-72] years, 2 persistent AF). The ablation strategy was PV isolation for paroxysmal AF and single ring box isolation for persistent AF, using MiFi catheter. The correlation of the generator impedance (GI) drop and LI drop after radiofrequency applications and the predictive value of the initial LI elevation before radiofrequency applications for LI drop were analyzed. Also, the LI and GI drop were investigated according to the location of RF applications. RESULTS The LI drop was higher than GI drop (23.7 [16.4-35.7] and 9.0 [6.0-12.0]; P < .01). There were correlations between the initial LI elevation and LI drop (R 2 = 0.466, P < .01) and between the LI and GI drop (R 2 = 0.263, P < .01). The LI drops significantly differed according to the different anatomical localizations by the Kruskal-Wallis test, although the GI drops did not differ (P < .01 and P = .49, respectively). CONCLUSION LI drop was associated with initial LI elevation and was larger than GI drop. LI drop was different according to locations, although GI drop was not. These findings might indicate that LI drop would be a more sensitive marker for lesion formation than GI drop.

Abstract
BACKGROUND Depression and anxiety are common mental health problems that are strongly associated with sleep disturbances, according to community-based researches. However, this association has not been investigated among patients admitted for cardiovascular diseases (CVDs). We examined the prevalence of depression and anxiety in inpatients with various CVDs and their association with sleep disturbances. MATERIALS AND METHODS This cross-sectional study included 1294 patients hospitalized for CVDs in a Japanese university hospital were evaluated for their mental status using the Hospital Anxiety and Depression Scale (HADS), for sleep-disordered breathing (SDB) using pulse oximetry, and for sleep quality using the Pittsburgh Sleep Quality Index (PSQI). RESULTS Patient characteristics were as below: mean age, 63.9±14.7 years; 25.7% female. Overall, 18.9% had depression (HADS-depression≥8) and 17.1% had anxiety (HADS-anxiety≥8). The presence of depression was associated with female sex, older age, higher plasma brain natriuretic peptide level, lower estimated glomerular filtration rate, and the prevalence of heart failure. Overall, 46.5% patients were categorized as having a poor sleep quality (PSQI>5), and 28.5% patients had SDB (3% oxygen desaturation index>15). Although depression and anxiety were not associated with SDB, they were independently associated with poor sleep quality (OR = 3.09, 95% CI 2.19-4.36; OR = 3.93, 95% CI 2.71-5.69, respectively). CONCLUSIONS Depression and anxiety were not uncommon in patients with CVDs. Poor sleep quality could be an important risk factor linked to psychological disturbances.

Abstract
OBJECTIVES This study sought to investigate whether symptom under-recognition is associated with the application of catheter ablation. BACKGROUND Atrial fibrillation (AF) symptom burden is frequently under-recognized and may affect the choice of treatment strategies. METHODS A total of 3,276 patients with AF consecutively registered in a Japanese multicenter database from 2012 to 2017 were analyzed. All patients underwent AF symptom burden assessment via the symptom and daily activities domain within the Atrial Fibrillation Effect on QualiTy-of-life (AFEQT) questionnaire. For the present analysis, 1,173 symptomatic patients (AFEQT score ≤80) with a clinical indication for catheter ablation were included. Under-recognition of symptom burden was defined as no subjective complaints checked by physicians despite self-reported AFEQT scores ≤80. Logistic regression analysis identified the predictors associated with receiving catheter ablation. RESULTS Of the 1,173 patients (age: 68 ± 12 years, men: 61%) analyzed, 459 underwent catheter ablation (ablation group); they had lower overall AFEQT scores (p < 0.01 for all domains) compared with the nonablation group. At the 1-year follow-up, greater improvement in the AFEQT scores was noted in the ablation group, even after adjusting for clinically relevant factors (+20.0 ± 1.2, +14.2 ± 0.9, respectively; p < 0.001). Notably, 306 (28%) patients met the criteria for symptom under-recognition, which was associated with the nonuse of catheter ablation during follow-up (odds ratio: 0.41; 95% confidence interval: 0.28 to 0.60; p < 0.001). CONCLUSIONS Under-recognition of AF symptom burden was frequently noted and was associated with less use of catheter ablation. Standardized recognition of symptoms using the application of validated questionnaires may facilitate outcome improvement.

Abstract
Background
Cryoballoon ablation (CBA) is a widely used procedure for atrial fibrillation (AF). However, the anatomical change of pulmonary veins (PVs) and the risk factors of PV stenosis is less clear. We aimed to decipher the prevalence and the predictive factors for PV stenosis after CBA.
Methods
We analyzed the data of 320 PVs from 80 patients who underwent CBA for AF (age: 62±10 years, 59 males, 75 paroxysmal AF). All patients underwent pre- and post-procedural cardiac computed tomography (mean 6.7±3.3 months after ablation). We defined the PV stenosis when the cross sectional area of PV was less than 50% compared with that of PV before the CBA.
Results
The average cross sectional PV area decreased significantly after CBA (pre- vs. post-CBA; 2.4±1.0cm2 vs. 2.3±1.1cm2, P<0.001), whereas the volume of left atrium (LA) also decreased significantly (pre- vs. post-CBA; 75.0±23.2cm3 vs. 70.7±21.9cm3, P<0.001). There was a weak but significant correlation between the reduction rate of PV area and that of LA volume (Pearson's correlation coefficient 0.411, p<0.001). Only 6 PV stenosis were revealed, in which area reduction of more than 75% and 50–75% were observed in 2 PVs and 4 PVs, respectively. The incidence of PV stenosis was greater in female (male vs. female; 0.8% vs. 4.8%, P=0.043) and tend to be frequent in left PVs (left PVs vs. right PVs; 3.1% vs. 0.6%: P=0.107). Moreover, patients who developed PV stenosis tended to have lower weight and shorter height (PV stenosis group vs. non-PV stenosis group; 58.2±12.4kg vs. 67.7±13.0kg: P=0.078, 161.2±9.1cm vs. 167.2±8.8cm: P=0.094). There were no significant differences in the number of freezing, minimum temperature and total freezing time between PV stenosis group and non-PV stenosis group.
Conclusions
The ostial PV area decreased significantly but little after CBA, possibly due to LA reverse remodeling. The PV stenosis was more common in women and tend to be frequent in left PVs, lower weight, and shorter height patients, though severe stenosis after CBA was not observed in this study.

Abstract
BACKGROUND The anatomical changes in pulmonary veins (PVs) after cryoballoon ablation (CBA) are unclear. We aimed to determine the morphological changes in the PVs and left atrium (LA) along with the predictive factors for clinical PV stenosis. METHODS We analyzed data of 320 PVs from 80 patients who underwent CBA for atrial fibrillation (age: 62 ± 10 years, 59 males). All patients underwent pre- and post-procedural cardiac computed tomography. We defined clinical PV stenosis when the cross-sectional area decreased by more than 50%. RESULTS The average ostial PV area and LA volume decreased significantly after CBA (pre- vs post-CBA; 2.4 ± 1.0 cm2 vs 2.3±1.1 cm2 , P < .001, 75.0 ± 23.2 cm3 vs 70.7 ± 21.9 cm3 , P < .001, respectively). There was a significant correlation between the reduction rates of the PV area and those of LA volume (R = 0.411, P < .001). The larger preoperative PV area and greater reduction in LA volume were associated with advanced PV narrowing. Clinical PV stenosis was observed in six PVs, was more common in females (male vs female; 0.8% vs 4.8%, P = .043), and tended to be more frequent in left PVs (left PVs vs right PVs; 3.1% vs 0.6%: P = .107), irrespective of the LA volume reduction. CONCLUSIONS The significant reduction of the ostial PV area occurred after CBA, which correlated with the reduction rate of LA volume. The narrowing of the PV was partly produced by the LA volume reduction. Clinical PV stenosis was more common in females and tended to be more frequent in left PVs.

Abstract
Our aim was to investigate the variability in physician recognition of atrial fibrillation (AF)-related symptoms, which greatly contributes to the management of AF patients. METHODS AND RESULTS: A total of 1493 newly-referredAF patients (67 ± 11 y/o, 1057 men) consecutively registered in an outpatient-based Japanese multicenter database (KiCS-AF) from September 2012 to December 2016 were analyzed. Self-reportedAF symptom burden was assessed via symptom and daily activities domains within the Atrial Fibrillation Effect on QualiTy-of-life (AFEQT) questionnaire. Physician symptom under-recognition (UR) was defined as no subjective complaints recorded in the medical records despite AFEQT score of <80; and physician's apparent over-recognition (OvR) was defined as documentation of subjective complaints despite total AFEQT score of ≥80. There was poor agreement between patient-reported and physicians-estimated symptom burden (kappa 0.28, 95% CI 0.23 to 0.33). In the logistic regression analysis, age> 75 (odds ratio [OR], 1.72; 95% confidence interval [CI], 1.13-2.62), male sex (OR, 1.82; 95% CI, 1.22-2.74), and persistent/permanent AF (OR 2.54/3.36; CI, 1.63-3.99/1.91-5.89, respectively) were predictors of UR. Conversely, heart failure (OR, 2.46; 95% CI, 1.44-4.25) and treatment in an ablation facility (OR, 1.43; 95% CI, 1.02-2.02) were associated with greater odds of OvR in addition to age, sex, and type of AF. CONCLUSIONS: Discordance in recognition of AF symptom burden by physicians was frequent in AF patients seen in outpatient management and involved both patient- and physician-related factors.

Abstract
INTRODUCTION An electrical superior vena cava (SVC) isolation from the right atrium (RA) sometimes can be challenging. For a safe and efficient SVC isolation, we aimed to visualize the accurate position of the SVC-RA junction on a three-dimensional (3D) mapping system using the decremental conduction properties of the SVC-RA junction in patients with atrial fibrillation (AF). METHODS This study consisted of 15 consecutive AF patients (11 males, age 59 ± 10 years). A 3D mapping catheter was positioned in the SVC-RA junction region while delivering a single extra-stimulus from the right atrial appendage (RAA), to discriminate the RA and SVC potentials. The electrophysiological SVC-RA junction was defined as the most proximal points where the SVC potentials were recorded, which were tagged on the 3D mapping system around the SVC-RA junction, where radiofrequency energy applications were applied. RESULTS Around the SVC-RA junction, 9 ± 2 points were tagged on the 3D mapping system. The highest and lowest SVC-RA junction points were located on the anterior wall and posterior wall, respectively. The difference in the level between the highest and lowest SVC-RA junction points was 16.2 ± 6.3 mm. A successful SVC isolation was obtained in all patients without any complications. CONCLUSION The plane of the electrophysiologically defined SVC-RA junction was not perpendicular to the body axis, but slanted due to the anterior side being higher. Recognizing the precise location of the SVC-RA junction would contribute to a safe and efficacious SVC isolation.

Abstract
BACKGROUND Rhythm-control strategy, including catheter ablation (CA) application, constitutes an integral part of atrial fibrillation (AF) management. However, elderly patients are underrepresented in clinical trials, and reports on patient-reported outcome of various rhythm-control treatments remain limited. Therefore, we aimed to investigate the application of a rhythm-control strategy for elderly patients with AF. METHODS Using a prospective, multicenter Japanese registry, we analyzed 733 patients with AF aged ≥70 years who completed the Atrial Fibrillation Effect on Quality-of-Life (AFEQT) questionnaire at baseline and 1-year visit. Improvement in patient-reported quality-of-life (QOL) was assessed according to their initial treatment strategy. RESULTS A total of 321 patients (43.8%) were managed with rhythm-control strategy, of which 125 (17.1%) received treatment with antiarrhythmic drugs (AADs) alone and 196 (26.7%) underwent CA. Compared with the rate-control group, the rhythm-control group was younger and less likely to have comorbid conditions but had lower baseline AFEQT-overall summary (OS) scores (71.8 [standard deviation 20.3] vs. 80.0 [standard deviation 16.1]; P < .001). After the first year, AFEQT-OS scores improved regardless of treatment strategies (ie, rate- or rhythm-control). After adjusting for confounders, CA implementation and a lower baseline AFEQT score were associated with meaningful improvement in QOL (changes in AFEQT-OS score ≥5). QOL improvement among subgroups of rhythm-control patients with AADs alone was not clinically meaningful. CONCLUSIONS In contemporary Japanese clinical practice, rhythm-control strategy is widely implemented in elderly patients with AF, and CA use is associated with improvement in QOL in carefully selected patients.

Abstract
A 23-year-old female had been suffering from recurrent syncopal episodes during sleep since her childhood. She had a family history of sudden death and her QTc interval was remarkably prolonged to 537 ms A Holter ECG revealed torsade de pointes, corresponding to syncope. She was started on mexiletine and her QTc interval shortened. Her symptoms were controlled after β-blockers and Ca-blockers were added. A genetic analysis with a next generation sequencer identified a frameshift mutation at the C terminus of the KCNH2 gene. Here we present a type 2 long QT syndrome case in which mexiletine was effective.

Abstract
PURPOSE Besides the high rates of morbidity and mortality, atrial fibrillation (AF) is also associated with impairment of quality-of-life (QOL). However, reports covering non-selected AF population within Asian countries remain scarce. The objective of the Keio interhospital Cardiovascular Studies-atrial fibrillation (KiCS-AF) registry is to clarify the baseline and QOL profiles of the AF patients at the time of initial referral to identify areas for improvement and country-specific gaps. PARTICIPANTS The KiCS-AF registry is a multicentre, prospective cohort study designed to specifically recruit AF patients newly referred to the 11 network hospitals within the Kanto area of Japan. The registry completed its enrolment in June 2018. All patients were requested to answer the Atrial Fibrillation Effect on Quality-of-Life (AFEQT) questionnaire both at baseline and 1 year, with planned clinical follow-up for 5 years. The registry also assessed individual treatment strategies including rate and rhythm control, stroke prophylaxis, and their impacts on patient-reported QOL. FINDINGS TO DATE As of December 2016, 2464 AF patients were registered; their mean age was 67.1 years (SD, 11.7), majority (69.7%; n=1717) were men and 49.2% presented with paroxysmal AF. The mean CHA2DS2-VASc (cardiac failure or dysfunction, hypertension, age ≥75 years, diabetes, stroke including vascular disease, age 65-74 years, and sex category [female]) score was 2.3 (SD, 1.6) and oral anticoagulant therapy was used for 88.6% of patients with CHA2DS2-VASc scores ≥2. The median AFEQT-overall summary score was 79.1 (IQR, 66.6-89.1). Roughly 50% had significantly impaired QOL (ie, AFEQT <80) at baseline. Currently, 2307 eligible patients (93.6%) have completed the 1-year follow-up, of which 2072 patients (89.8%) answered the second AFEQT questionnaire. FUTURE PLANS The KiCS-AF allowed for extensive investigation of AF-related QOL in a non-selected population with long-term follow-up using a rigorously validated QOL assessment tool. Almost half of patients had impaired QOL at baseline. Further investigations aimed at providing care and improving patient-reported QOL are required.

Abstract
INTRODUCTION Restoration of sinus rhythm (SR) by catheter ablation (CA) of atrial fibrillation (AF) improves exercise tolerance. However, it is still unclear what characteristics of patients are contributing to an improvement in exercise tolerance after CA of AF without heart failure. METHODS AND RESULTS This study consisted of 51 consecutive patients with persistent or long-standing persistent AF without heart failure who were restored to SR for over 6 months by a successful CA. Exercise tolerance was evaluated by cardiopulmonary exercise testing before and 3 and 6 months after CA. The clinical characteristics contributing to an improvement in exercise tolerance was elucidated. The peak oxygen uptake (VO2 )% significantly increased from 101.4 ± 20.3% to 110.9 ± 19.9% 3 months after the CA (P < .001). The improvement rate in the peak VO2 % exhibited a positive correlation to the baseline brain natriuretic peptide (BNP; ρ = 0.39, P < .01), but not to the age, AF duration, left ventricular ejection fraction, or left atrial size. The linear regression analysis revealed that the baseline BNP was an independent predictor of an improvement in the peak VO2 % (coefficients = 0.32; 95% confidence interval = 0.08, 0.54; P = .01). The peak VO2 % improved significantly in the patients whose baseline BNP level was greater than 100 pg/mL, compared to the others (P < .01). These favorable findings were also observed 6 months after the CA. CONCLUSION Elimination of persistent AF by CA was associated with an improvement in exercise tolerance. This was particularly true in patients with high BNP values at baseline.

Abstract
Aims To confirm the presence of tachycardia-induced slur or notch in the terminal portion of the QRS complexes in a general patient population. Methods and results A tachycardia-induced J wave was defined as a slur or notch in the terminal portion of the QRS complexes newly induced at short RR intervals during atrial premature contractions (APCs) or atrial electrical stimulation in the electrophysiological study (EPS). Twenty-three out of 2000 patients with general diseases were involved. All patients with aborted sudden cardiac death, ventricular fibrillation or a family history of sudden cardiac death were excluded. The mean age was 72 ± 9 years, and 11 patients were male (47.8%). When the RR interval was shortened from 821 ± 142 ms to 464 ± 52 ms in the conducted APCs (P < 0.0001), J waves became diagnostic (0.02 ± 0.03 mV to 0.20 ± 0.07 mV, P < 0.0001). J waves were confined to the inferior leads in 22 (95.7%) patients and were notched in 11 (47.8%) and slurred in 12 (52.2%) patients. The induction of J waves was accompanied by visible changes of the QRS morphology. When the post-APC RR interval was prolonged to 992 ± 305 ms (P = 0.0154 vs. baseline), the J waves were similar to baseline levels. During the EPS, J wave induction was confirmed during atrial stimulation. There were no characteristic clinical or ECG features in the patients with tachycardia-induced J waves. Conclusions J waves can be newly induced by short RR intervals in a general patient population, and a conduction delay is the likely mechanism causing such J waves.
