Abstract
PURPOSE The evolution of heart rhythm monitoring technology over the past few decades has seen a decline in the use and need of transtelephonic monitoring (TTM). We sought to establish a predicted date for the sun setting of TTM at our institution, as well as establish the current demographics of the patients still using this technology. METHODS We retrospectively reviewed all patients with permanent pacemakers receiving routine device follow-up at our institution (Mayo Clinic-Rochester) between 2015 and 2018. From this cohort, we reviewed and analyzed patients using TTM for device follow-up and utilized projected battery longevity to determine cessation date. Pacemaker implantation date, underlying arrhythmia, and most recent device interrogation reports were also collected. RESULTS As of March 2018, a total of 3543 patients with permanent pacemakers were being followed at our institution and 289 (8.2%) are using TTM for monitoring device function (147 male, mean age 79.9 ± 12.0 years). Of those currently using TTM, by January of 2020, only 122 (42.2%) are predicted to be using this technology for device follow-up, 40 (13.8%) by January 2022, with zero patients by November of 2024. CONCLUSIONS The use of TTM will continue to significantly diminish over the next few years. Based on battery longevity estimates, we predict that by the end of 2024 TTM will no longer be used for device follow-up at our institution.

Abstract
BACKGROUND To determine the sensitivity and specificity, rate of compliance, and predictors of failure of telephone transmission of pacemaker function in a pediatric population. METHODS A total of 2,638 pacemaker transmission records were reviewed retrospectively. Standard calculations of sensitivity, specificity, and positive and negative predictive values were performed. Longitudinal data analysis was used to detect factors influencing the effectiveness of transtelephonic monitoring. The proportion of missed transmissions was calculated, thus enabling assessment of compliance. Logistic regression was performed to determine predictors of poor compliance. RESULTS Telephone transmission of pacemaker function, as a diagnostic tool, had a sensitivity of 94.8%, specificity of 99.2%, positive predictive value of 82.1%, and negative predictive value of 99.9%. Longitudinal analysis failed to show any significant predictors of transmission failure. Compliance with a prescribed transmission reached 84.5% in our patient population. Logistic regression analysis failed to identify any predictors of noncompliance. CONCLUSION Values for sensitivity and specificity indicate that telephone transmission is a useful diagnostic tool for assessing pacemaker function at a distance. Negative predictive value is 99.9%, indicating that normal telephone transmissions are very reassuring of normal pacemaker function. Telephone transmission is equally successful in all age groups, genders, distances from a tertiary referral center, underlying diagnoses, pacing modes, and pacemaker models. Compliance with telephone transmission follow-up was higher in our population than in previous studies.

Abstract
This pilot study focuses on pacemaker follow-up in the technically stable period 1-5 years after a pacemaker implantation. Two hundred and thirty selected patients with single chamber pacemakers (215 VVI, 15 AAI) had their follow-up intervals prolonged to 2-4 years in this period. Sixty-six patients fulfilled the study period uneventfully and 21 are still pending. Sixty-nine patients had unscheduled visits to the pacemaker clinic. Of these, 7 were reoperated (1 for exit block, 4 had pocket erosions, and 2 were upgraded to DDD). Nine were reprogrammed (1 for sensing failure, 1 had the pulse duration increased, and in 7 the pacing rate was changed). Seventy-four patients died. In 63, the cause of death is known not to be pacemaker related. Six died suddenly, and in five cases, the cause of death is unknown. This study indicates that frequent follow-up visits may be omitted in this period in selected patients with single chamber pacemakers. A prerequisite is that the patients are registered at a pacemaker clinic and have easy access to the physician whenever they suspect pacemaker related problems.

Abstract
The diagnostic accuracy of transtelephonic pacemaker monitoring (TTM) has been quantified in a retrospective study involving 369 patients in three U.S. cardiac centers. Using existing medical records, TTM findings in a total of 413 reports were judged for equivalence to the findings of subsequent physical examinations in pacemaker clinics. This study found TTM follow-up testing to have a sensitivity of 94.6%, specificity of 98.5%, positive predictive value of 93.3%, and negative predictive value of 98.8%. The study also documents the clinical utility of TTM in identifying various modes of pacemaker malfunctions and instances of significant arrhythmia.

Abstract
OBJECTIVE To review (1) Changes in cardiac impulse generation, conduction, and ventricular filling in normal aging and disease; (2) Pacemaker technology and nomenclature; (3) Expert guidelines about pacemaker use; (4) Studies of pacemaker effectiveness and utilization. DESIGN Articles were identified through a Medline search, review of articles' bibliographies, and contact with pacemaker manufacturer representatives for information on device features and costs. These articles were reviewed, and the relevant data are presented. RESULTS Abnormalities in impulse generation and conduction are common in the elderly. Pacemaker use is higher in the elderly than in other population groups. Hemodynamic changes associated with aging include an increased contribution of atrial contraction to ventricular filling. Pacemakers, which maintain the synchrony between the atria and ventricles, may be particularly advantageous in the elderly for this reason. Rate-responsive ventricular pacemakers improve the quality of life compared with fixed rate devices in some patients over the age of 75. Dual-chamber, sequential pacemakers are more likely to reduce symptoms of pacemaker syndrome than ventricular pacemakers and probably also prolong survival and reduce risk of atrial fibrillation in certain groups of patients. However, dual chamber devices are more expensive and require more frequent follow-up. Pacemaker utilization can vary widely by region. Decisions about pacemakers require explicit tradeoffs between risk and quality of life on one hand and cost on the other. In many clinical situations, there is controversy as to whether pacemakers should be used. CONCLUSIONS Pacemakers provide definite benefits to some patients, whereas in others, the likelihood of benefit is uncertain. More sophisticated devices may provide some additional benefit, but they are more costly. Further data is still required to define precisely which groups of patients substantially benefit from complex and expensive pacing modalities compared with simpler ones.

Abstract
BACKGROUND Permanent cardiac pacing is well established for the improvement of prognosis and quality of life in patients with severe bradycardia. However, sudden cardiac death still remains an unresolved problem, as it occurs in approximately 20-30% of paced patients. This 2-year follow-up study was directed at prospectively assessing prevalence, circumstances, and mechanisms of sudden death in 2,021 permanently paced patients. METHODS AND RESULTS During the observation period, 220 patients (11%) died (mean pacing interval, 50.5 +/- 7 months). Lethal cerebrovascular events in 66 of 220 patients (30%) and sudden death in 49 of 220 patients (23%) were the two most frequently reported modes of death. Nonsudden (first year, 20%; subsequent years, 6.9%; p less than 0.01) and sudden death mortality rate (4% versus 1.8%, p less than 0.05) were highest during the first year. Mortality was unrelated to the patient's activity status at the time of death. Sudden cardiac death occurred more often in male patients (increased risk, 1.7 versus female patients; p less than 0.001) and patients younger than 60 years of age (5.2 versus patients older than 60 years, p less than 0.001). Patients with severe bradycardia (sudden death rate, 28%), severe atrioventricular block (25%), or atrial fibrillation with low ventricular rate (25%) before pacemaker implantation were more likely to suffer from sudden cardiac death than patients with previous syncopal attacks (sudden death rate, 15%) or sick sinus syndrome (17%). The highest incidence of sudden death was observed in patients with bifascicular and trifascicular bundle branch block. In this group, 35% of patients died suddenly during the follow-up period compared with 18% of patients without bundle branch block. In a subsequent study in 90 consecutive patients with various types of bundle branch block, undersensing of up to 13% of ectopic ventricular beats occurred in patients with bifascicular block. Pacing-induced tachyarrhythmias and ventricular fibrillation were documented in 10% of undersensed ectopic ventricular beats as well as in the setting of atrial fibrillation associated with ventricular arrhythmias. CONCLUSIONS Young age, male sex, and a severely diseased heart indicated by the presence of bifascicular and trifascicular bundle branch block are the strongest predictive clinical parameters for sudden cardiac death, especially in the first year after pacemaker implantation.

Abstract
This report reviews recent pacemaker technological advances as they apply to infants, children, and adolescents. Indications for pacemaker implantation in children have evolved since the 1984 Joint Task Force Guidelines. Recent data show that pacemaker implantation should be strongly considered in patients who have (1) asymptomatic congenital complete AV block with a mean heart rate less than 50 beats/min or other evidence of junctional instability; (2) congenital AV block with long QT interval; or (3) congenital long QT syndrome with bradyarrhythmias, or when conventional beta-blocker therapy is unsuccessful. Permanent pacemaker implantation is not necessarily an effective prophylactic measure against sudden death in patients following their operation who are receiving drug therapy for atrial tachyarrhythmias, and so is not absolutely indicated. New developments in lead technology have made transvenous lead systems more feasible for pediatric use. Because epicardial leads are required for small infants and for cosmetic reasons in some older children, design improvements are needed to enhance epicardial lead performance. Rate-responsive pacing is an acceptable alternative to dual-chamber pacing for augmenting exercise tolerance, and for children with sinus node dysfunction it is the preferred pacing mode. Pacemakers with automatic antitachycardia capabilities and with noninvasive electrophysiology features are valuable in children with atrial tachyarrhythmias. New data suggest that chronic atrial pacing also may be effective in controlling atrial tachyarrhythmias. New developments in pacemaker systems for the young parallel those for the older population, but differences between adult and pediatric patients demand ongoing increased participation by pediatric cardiologists.
