Abstract
INTRODUCTION During an acute migraine attack, changes in ventricular repolarisation parameters may occur due to an imbalance in the autonomic nervous system. Tpeak-tend (Tp-e) interval, Tp-e/QT ratio, and Tp-e/corrected QT (QTc) ratio are novel parameters of arrhythmogenesis and can be easily calculated in electrocardiography (ECG). The objective of this study is to demonstrate that novel ventricular repolarisation parameters can anticipate the risk of ventricular dysrhythmia in the migraine attack period. METHODS This research was a prospective case-control study, which recruited a total of 144 participants, including 74 migraine patients and 70 healthy volunteers in the control group (CG) who met the criteria for migraine with or without aura. All participants underwent 12-lead ECG recordings, and the study compared the Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio with those of the CG. RESULTS The average age of patients experiencing migraine attacks was 38.14 ± 10.82, with 58 (76%) of these patients being female. The Tp-e interval mean was higher in the migraine attack group than the CG, with a statistically significant difference discovered (74.22 ± 20.20 ms [ms] compared to 65.39 ± 11.33 ms, p = 0.001). However, there were higher mean Tp-e/QT and Tp-e/QTc ratios in the migraine attack group compared to the CG, and this difference was found to be statistically significant (0.20 ± 0.05 vs. 0.17 ± 0.03, p = 0.001, 0.18 ± 0.52 vs 0.16 ± 0.29, p = 0.003, respectively). CONCLUSION Prolonged Tp-e interval and elevated Tp-e/QT and Tp-e/QTc ratios were observed in migraine patients who presented to the emergency department, indicating a potential risk of ventricular dysrhythmia.

Abstract
BACKGROUND Exclusion of stroke is the focus of guidelines in the emergency department assessment of acute vertigo, especially with new-onset atrial fibrillation (AF). Early diagnosis of vestibular neuritis (VN) is also important but may be deferred awaiting brain magnetic resonance imaging (MRI) for exclusion of stroke. This may delay potentially beneficial corticosteroid therapy. AIMS To highlight that VN can provoke acute AF. METHODS In the course of a prospective study of acute vertigo in patients assessable within 24 h of admission, we encountered three patients with acute onset transient AF associated with VN. We performed a detailed neurological examination and quantitated the vestibulo-ocular reflex (VOR) gain with video-oculography. Brain MRI was performed in all patients. RESULTS There were two men and one woman, aged 58-66 (mean 61) years. All patients had typical non-direction-changing rotatory nystagmus and positive head impulse tests. The horizontal VOR gains ranged 0.38-0.62 (mean 0.47). Diffusion-weighted MRI within 36 h was normal in all. AF reverted in all three within 24 h. CONCLUSIONS Acute AF can be precipitated by vertigo such as in VN. In VN, the concurrence of acute AF may distract from the correct neurological diagnosis, delaying potentially beneficial corticosteroid therapy, especially if exclusion of stroke is dependent on MRI, which may be delayed.

Abstract
Migraine is a common neurological disorder affecting 12% of the global population. The common risk factors are adolescent age, genetics, and female sex, and are triggered by hormonal fluctuations, emotional stress, sensory overload, weather changes, alcohol consumption, fasting, cheese, chocolate, smoked fish, yeast extract, cured meats, artificial sweeteners, food preservatives containing nitrates and nitrites, and sleep disturbances. Migraine with aura is associated with an increased risk of cardiovascular disease events, such as myocardial infarction, angina pectoris, and cardiac arrhythmias, and has recently been added to the QRISK3 cardiovascular disease prediction score. Population-based cohort studies have shown a significant association of migraine with aura and cardiac arrhythmias, most importantly atrial fibrillation. Patients suffering from migraine with aura are at an increased risk for cardiac arrhythmias; thus, it is essential to screen these patients for undiagnosed cardiovascular disorders.

Abstract
BACKGROUND AND AIM Migraine patients can exhibit autonomic dysregulation, in turn leading to cardiac conduction and repolarization abnormalities. This systematic review and meta-analysis evaluated the electrocardiographic changes in migraineurs. METHOD PubMed and Embase databases were searched for human studies using the search terms 'migraine' and 'electrocardiogram' until 15th December 2018, identifying 108 and 131 studies. RESULTS Thirteen studies involving 667 migraineurs and 208 normal subjects included (mean age=30.7, total male percentage=19.8%) were included. A longer mean QTc interval (standard mean difference=7.89, 95% confidence interval=[3.29, 12.49], p=0.0008) and higher frequency of QTc prolongation (risk ratio [RR]=6.23, [2.86-13.58], p<0.00001), but no difference in PR-interval (SMD=4.33, [-3.90-12.56], p=0.30) were observed during migraine attacks compared to pain-free periods. P-wave dispersion was higher in migraine patients compared to controls (mean difference=3.62, [1.03-6.21], p=0.006). RR-interval were statistically indistinguishable between migraine patients and controls (SMD=0.08, [-0.65-0.81], p=0.83), or between migraineurs with and without aura (SMD=-0.03, [-0.44-0.38], p=0.89). Deep breathing ratio was significantly lower in migraineurs compared to controls (SMD=-0.27, 95% CI=[-0.46, -0.08], p=0.006) but similar between migraineurs with and without aura (SMD=-0.04, [-0.27-0.19], p=0.74). No significant difference in Valsalva ratio is found between migraineurs and controls (SMD=0.10, [-0.32-0.53], p=0.63) or between migraineurs with and without aura (SMD=-0.17, [-0.40-0.06], p=0.14). Root mean square of successive differences (RMSSD) (SMD=-0.07, [-1.10-0.95], p=0.89) and standard deviation of NN intervals (SDNN) (SMD=-0.10, [-0.61-0.41], p=0.71) did not significantly differ between migraine patients and controls. CONCLUSION Electrocardiographic alterations are observed in migraine patients compared to controls, especially during migraine attacks.

Abstract
INTRODUCTION Migraine is a common neurovascular disease characterised with recurrent attacks by pain-free periods. It has been suggested that both sympathetic and parasympathetic dysfunctions play a role in its pathophysiology. AIM The aim of our study was to investigate the ECG changes during attack-free period in children with migraine, in terms of QTc interval, QTc, and P-wave dispersion to evaluate the autonomic nervous system disturbance. METHODS Sixty children who were diagnosed with migraine were included as patient group and 50 healthy, age- and body mass index-matched children who were examined for innocent murmur were included as control group. The patients' routine ECG records were screened from the outpatient clinic files. The durations of P-wave, QT, and QTc intervals and dispersion values and heart rates (beats/minute) were compared between the patient and control groups. RESULTS P maximum and P dispersion were significantly higher, and P minimum was significantly lower in the migraine group compared with the control group. QT-QTc maximum and QT-QTc dispersion were significantly higher and QT-QTc minimum was significantly lower in the migraine group compared with the control group. CONCLUSION According to our findings, although migraine patients were asymptomatic and no arrhythmia was detected in the surface ECG, sympathovagal balance in the sympathetic system, which may be disrupted in favour of the sympathetic system, should continue even in the attack-free period, and we should be careful in terms of serious arrhythmias that may develop in these patients.

Abstract
AIMS Migraine is a chronic neurovascular disorder characterized by intermittent episodes of severe headache. Abnormalities in the autonomic nervous system (sympathetic and parasympathetic nervous systems) have been detected during migraine-free periods in patients with migraine. In these patients, disrupted autonomic innervations of the heart and coronary arteries may lead to electrocardiographic changes during a migraine attack. T-wave peak-to-end interval (Tp-e interval) and Tp-e/QT ratio are relatively new markers of ventricular arrhythmogenesis and repolarization heterogeneity. In the present observational study, we investigated the changes in ventricular repolarization during migraine attacks and attack-free periods by performing 12‑lead electrocardiography (ECG). METHODS This study included 63 patients (54 [86%] women; mean age: 33.3 ± 9.9 years) with migraine. The QT and corrected QT (QTc) intervals, Tp-e interval, and Tp-e/QT ratio of the patients during migraine attacks and attack-free periods were measured by performing 12‑lead ECG. RESULTS The QT and QTc intervals, Tp-e interval, and Tp-e/QT ratio were higher during migraine attacks than during attack-free periods (P < 0.001 for all). CONCLUSION These results indicate that migraine attacks are associated with an increase in ventricular repolarization parameters compared with attack-free periods possibly because of the dysregulation of the autonomic nervous system.

Abstract
OBJECTIVES Migraine headache is common in pediatrics and is frequently assessed in emergency departments. Altered cardiac conduction, including prolongation of the QTc interval on electrocardiogram, has been observed in adults during migraine headache and resolves interictally. Prolonged QTc is associated with life-threatening arrhythmia, and many acute and prophylactic therapies for migraine can further prolong the QTc interval. It is the objective of this prospective cohort study to examine whether the QTc interval prolongs significantly during periods of acute migraine headache in children. METHODS Patients ages 6 to 17 years presenting to the emergency department with acute migraine headache were recruited prospectively. Exclusion criteria included the use of QTc-prolonging medications and medical illnesses, including cardiovascular abnormalities, infection, or head injury. Paired, one-tailed Student t tests compared QTc intervals with and without headache and evaluated for QTc prolongation of 30 ms or longer during headache. RESULTS Thirteen patients with migraine (mean age, 11.6 ± 2.6 years) were evaluated. Mean QTc interval during headache was significantly longer than the QTc interval in the absence of headache (437.9 ± 27.7 ms compared with 419.3 ± 29.9 ms; p = 0.04). Three patients (23%) had unequivocal prolongation of the QTc (>460 ms) during the migraine, two of which normalized with headache resolution. The mean increase in QTc during headache did not reach or exceed 30 ms (p = 0.86) CONCLUSIONS: This study is the first to illustrate a connection between QTc prolongation and acute migraine headache in children. If confirmed in future studies, children should be monitored for QTc prolongation during the acute treatment of migraine in the emergency department when using medications that can lengthen the QTc interval.

Abstract
Evidence suggests that symptoms of migraine are related to the involvement of the autonomic nervous system. Data on atrial conduction system are limited in migraineurs. We aimed to assess atrial electromechanical delay using tissue Doppler imaging (TDI) in patients with migraine. Forty-five migraine patients and age- and sex-matched 26 control subjects were enrolled in the study. All the patients and controls underwent resting surface electrocardiogram (ECG) and TDI. The maximum P-wave duration (Pmax), minimum P-wave duration (Pmin) and P-wave dispersion (Pd) were measured from the 12-lead ECG. Atrial conduction time was determined from the lateral mitral annulus (PA lateral), septal mitral annulus (PA septal), and lateral tricuspid annulus (PA tricuspid) by TDI. Interatrial (PA lateral-PA tricuspid) and intraatrial (PA septal-PA tricuspid) electromechanical delays were calculated. Pd was significantly higher in migraine patients than in controls (p < 0.05), whereas Pmax and Pmin were not different between both groups (p > 0.05). PA lateral and PA septal durations were significantly higher in migraine patients than in controls (p < 0.001 and p < 0.05, respectively). However, PA tricuspid duration was similar between the groups (p > 0.05). Both interatrial and intraatrial conduction times were delayed in migraineurs as compared to the controls (p < 0.001). Interatrial delay and intraatrial delay variables were found as an independent risk factors separately on predicting atrial conduction abnormalities in migraineurs. An interatrial delay of 18 ms and an intraatrial delay of 5 ms were found to be cutoff values in ROC analysis (p < 0.001). This is the first report to provide a hypothetical suggestion that there is an atrial electromechanical delay in patients with migraine.

Abstract
Cardiac manifestations of neurologic diseases are common in clinical practice. There are numerous anatomic and pathophysiologic links between the normal and abnormal function of both systems. There are a number of brain-heart interactions which affect the care of patients as well as help guide therapeutic development. This is exemplified in the area of vascular neurology where knowledge of the brain-heart connection is essential not only for bedside management but where collaborative efforts between neurology and cardiology are key in developing new strategies for ischemic stroke prevention and treatment, atrial fibrillation, and interventional techniques. This chapter will focus on cardiac manifestations of neurologic disease, with special emphasis on vascular and intensive care neurology, epilepsy, and neurodegenerative and peripheral nervous system diseases.

Abstract
Objective: To determine whether or not wave/interval dispersions in electrocardiography (ECG) are increased, and to define whether wave and interval dispersions are correlated with carboxyhemoglobin (COHb) levels. Methods: ECG, complete blood count, and biochemical parameters were taken from 87 patients with carbon monoxide (CO) poisoning as well as 90 control patients with similar age, gender, and body mass index distribution. COHb levels were recorded in CO-poisoning patients. The COHb levels and the relationships with ECG parameters were studied. Results: Pmax, Pmin, Pd, PRmax, PRmin, PRd, QTmax, QTmin, QTd, cQTmax, cQTmin, cQTd, Tmax, Tmin, and Td in ECG were higher in intoxicated patients than the control group ( p < 0.05 for all). Pearson’s correlation analyses showed moderately significant positive correlations between COHb level and Pmax ( r = 0.224; p = 0.037) and Pd ( r = 0.222; p = 0.039). The receiver–operator characteristic (ROC) curve showed that a Pd value of 38 ms determined by ECG separates patients with a COHb ≥ 20% with area under the ROC curve of 0.78 (95%CI = 0.71–0.83), a sensitivity of 67.9% (95%CI = 59.4–75.6), a specificity of 95% (95%CI = 83.0–99.2], a positive predictive value of 97.9% (95%CI = 92.5–99.7), and a negative predictive value of 46.3% (95%CI = 35.3–57.7.) Conclusion: A significant increase in wave/interval dispersions in the ECG of CO-poisoning patients compared with controls may show that not only a part is affected but both atrium and the ventricles as a whole are affected by hypoxic ischemia. When COHb levels of the patients are unavailable, P dispersion on ECG may show CO poisoning level of the patient.

Abstract
OBJECTIVE AND AIM An imbalance of the sympathetic system may explain many of the clinical manifestations of the migraine. We aimed to evaluate P-waves as a reveal of sympathetic system function in migraine patients and healthy controls. MATERIALS AND METHODS Thirty-five episodic type of migraine patients (complained of migraine during 5 years or more, BMI < 30 kg/m²) and 30 controls were included in our study. We measured P-wave durations (minimum, maximum, and dispersion) from 12-lead ECG recording during pain-free periods. ECGs were transferred to a personal computer via a scanner and then used for magnification of x400 by Adobe Photoshop software. RESULTS P-wave durations were found to be similar between migraine patients and controls. Although P WD (P-wave dispersion) was similar, the mean value was higher in migraine subjects. P WD was positively correlated with P max (P < 0.01). Attacks number per month and male gender were the factors related to the P WD (P < 0.01). CONCLUSIONS Many previous studies suggested that increased sympathetic activity may cause an increase in P WD. We found that P WD of migraine patients was higher than controls, and P WD was related to attacks number per month and male gender. Further studies are needed to explain the chronic effects of migraine.

Abstract
The aim of our study was to investigate P wave dispersion (Pwd), QT, corrected QT (QTc), QT dispersion (QTd) and corrected QT dispersion (QTcd) intervals in subarachnoid haemorrhage. Thirty-five subarachnoid haemorrhage patients (Group S) and 35 neurologically normal patients (Group C) were included in this retrospective study. The standard 12 derivations of the electrocardiograms of all patients were analysed and Pwd, QT and QTd intervals were measured. QTc and QTcd intervals were determined with the Bazett formula. There was no significant difference between the study groups according to demographic characteristics, hypertension and diabetes mellutus incidences (P >0.05). The Pwd, QT, QTc, QTd and QTcd durations of Group S were significantly longer than those of Group C (P <0.001). Subarachnoid haemorrhage patients may have a higher likelihood of arrhythmia during anaesthesia and in intensive care due to extended QTcd and Pwd durations.

Abstract
Extension of the QT interval is characterized by syncope and cardiac arrest and often occurs in association with medical therapies and procedures. Whether erythroapheresis (EPH) could influence the QT interval duration in patients with sickle cell disease (SCD) is not known. We aimed to investigate the effects of EPH on the heart rate-corrected QT (QTc) interval. The study included 25 patients with SCD who underwent 34 EPH procedures. Two independent observers measured QTc interval duration from electrocardiograms performed continuously for 3 min at three different points during the EPH procedures (prior to EPH, after completion of 50% EPH and 15 min after EPH). Multiple regression analysis was used to determine if the ionized plasma calcium, the level of plasma magnesium, citrate infusion rate and painful crisis significantly contributed to the QTc interval. There was a non-significant trend (P = 0.184) towards increased QTc in sickle cell patients during EPH compared with pre-EPH values. QTc prolongation (>440 ms) occurred in 72% of the procedures. Fifty percent QTc values returned to baseline after the procedure. The independent variables were not significantly associated with QTc interval. Exchange procedures can induce QTc prolongation in patients with SCD.
