Abstract Background Although sinus node dysfunction (SND) coexists with atrial fibrillation (AF) in some cases, SND in patients with Non-paroxysmal AF (Non-PAF) could not be estimated in conventional electrophysiological study. Atrial low voltage zone (LVZ), which may be surrogate for atrial fibrosis, is although reported to present in patients with Non-PAF, the association between SND and right atrial LVZ (RA-LVZ) has not been fully evaluated. The aim of the present study was to assess the relationship between SND and RA-LVZ in patients with Non-PAF. Method Eighty-six Non-PAF patients underwent high density voltage mapping of right atrium (RA) during AF before ablation procedure. We defined LVZ as that with electrogram amplitude <0.1 mV in order to delineate strongly damaged area in RA. We evaluated the surface are of the RA-LVZ in Non-PAF patients with and without SND. Results Twenty-seven of 86 patients (31.4%) presented with SND after AF termination. There were no significant differences between patients with and without SND in variables such as age, sex, AF duration, left atrial diameter, and left ventricular ejection fraction. The mean value of RA-LVZ of all the patients was 12.1±11.4%, and RA-LVZ was significantly larger in patients with SND than in those without SND (22.8±14.6 vs 7.2±4.2%; P<0.001). In multivariate logistic regression analysis for the incidence of subsequent pacemaker implantation (PMI), only RA-LVZ was a significant predictor of subsequent PMI (odd ratio 1.306; 95% confidence interval 1.159 - 1.473; P<0.001). Receiving-operating characteristic curve for PMI following ablation procedure indicated cut-off value 10.5% for RA-LVZ with 85.2% sensitivity and 88.1% specificity (area under curve = 0.924, P<0.001). Kaplan-Meier analysis of the incidence of PMI after AF termination showed that freedom from pacemaker implantation was significantly better in patients with RA-LVA <10.5% than in those with RA-LVZ ≥10.5% (log-rank test; P<0.001). Conclusions Broad RA-LVZ measured during AF was strongly associated with SND and PMI after AF termination in patients with Non-PAF. Evaluation of RA-LVZ during AF could be a potential target in predicting SND requiring PMI in patients with Non-PAF.

Background: To determine the demographic details, indications, type of pacemakers and complications in patients undergoing the permanent pacemaker implantation.Methods: This was a single-center, retrospective study conducted in at a tertiary-care center in India. The records of 200 patients who had undergone implantation of permanent pacemakers in the period of May 2016 to April 2018 were reviewed.Results: Total 200 patients with mean age of 67 years were paced. Of these 120 (60%) were males. The mean duration of hospital stay was 6.5 days. Sinus node disease (105 patients, 52.5%) was the most common indication for permanent pacemaker insertion. Single chamber (VVIR) pacing mode (125 patients, 62.5%) was found to be the most common pacing mode used for pacemaker insertion. Among the 200 patients complications were observed in 8 patients (4%). Of these 8 patients, pneumothorax (4 patients, 2%) was found to be the most common complication for permanent pacemaker implantation followed by local site infection (1 patient, 0.5%). Only 1 patient (0.5%) died during the observation period of the study.Conclusions: Geriatric population with male predominance have observed to commonly undergo permanent pacemaker implantation. Sinus node disease in the elderly patients is the most common indication for cardiac pacing followed by atrioventricular block. Single chamber (VVIR) pacing mode is commonly used followed by dual chamber (DDDR) due to economic reasons in India. Pacemaker implantation is a relatively safe procedure with a low complication rate.

Abstract Background： Patients implanted with pacemakers frequently develop atrial fibrillation. Pacemaker-detected atrial high-rate episodes or AHREs, where one AHRE is defined as ≥ 160beats/min lasting ≥ 5 minutes, may identify patients at increased risk for stroke and death. In this study, we sought to observe whether patients with sinus node dysfunction or atria-ventricular block are more likely to develop AHREs. Methods: A total of 103 patients (age 69.4±13.5 years，58% female) with DDD/DDDR pacemakers were enrolled for the study. These pacemakers were equipped with features that enabled the detection and storage of information such as the dates, durations and sequential episodes of AHRE. Patients were followed up for 2 years and the time of the first occurrence of AHRE was determined at follow-up visit. Other data such as age, gender, structural heart disease, concomitant non-cardiac diseases, the cumulative percentage of atrial pacing (Cum% AP) and ventricular pacing (Cum% VP) were also collected. Results: Atrial fibrillation developed frequently after the dual-chamber pacemaker implantation. AHRE occurred more often in patients with sinus node disease (SND) than those with atrioventricular block (AVB) （OR, 2.553; 95%CI, 1.122-5.814；P=0.045）. Conclusions: AHRE developed frequently after dual-chamber pacemaker implantation. Patients with SND are more likely to develop AF compared to the patients with AVB.
