Persistent Arrhythmogenic Effects of COVID‐19: A Comprehensive Analysis of Device Implantation and Antiarrhythmic Interventions in Japan

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
COVID‐19 was associated with a sustained increase in device implantation and arrhythmia‐related interventions over 2 years. In a nationwide propensity score‐matched cohort, risks of pacemaker, ICD, CRT implantation, ablation procedures, and antiarrhythmic medication initiation remained higher after COVID‐19, supporting long‐term cardiovascular ...

Electrophysiological Substrate and Ablation Outcomes in Atrial Fibrillation With Hypertrophic Cardiomyopathy: A Propensity‐Matched Multicenter Study

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
Multicentre retrospective propensity‐score‐matched cohort study (n = 286; 3 centres, Pakistan; 2015‐2023) comparing electrophysiological substrate and 12‐month ablation outcomes in patients with atrial fibrillation and hypertrophic cardiomyopathy (HCM‐AF, red) versus lone atrial fibrillation (Lone AF, green; 1:1 PSM on 14 covariates).

Electro‐Mechanical Dissociation in Chagas Cardiomyopathy: Comparative Analysis of Arrhythmic Burden Beyond LVEF

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
Despite matched clinical characteristics and LVEF, patients with Chagas cardiomyopathy exhibit a significantly higher arrhythmic burden compared to ischemic cardiomyopathy. This electro‐mechanical dissociation highlights the necessity of sudden death risk stratification strategies that extend beyond traditional ejection fraction thresholds.

Electrophysiological Characteristics of Atrial Fibrillation Trigger Sites During Ongoing Atrial Fibrillation Using Ultra‐High‐Resolution Mapping

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
AF trigger sites exhibited a markedly shorter minimum local cycle length during ongoing AF, suggesting transient rapid activity. Ultra‐high‐resolution mapping during ongoing AF may provide complementary mechanistic information when conventional trigger mapping is inconclusive.

The Efficacy of Left Atrial Appendage Occlusion During Thoracoscopic Epicardial AF Ablation for Improving Rhythm and Cardiac Function in Patients With Heart Failure

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
Thoracoscopic epicardial AF ablation in heart failure improved LV systolic function irrespective of left atrial appendage occlusion (LAAO). Concomitant surgical LAAO was associated with fewer LPV reconnections without worsening postoperative diastolic function, while atrial tachyarrhythmia recurrence was similar between groups.

Association Between Left Ventricular Diastolic Dysfunction and Subsequent Detection of Sick Sinus Syndrome and Atrial Fibrillation in Patients With Unexplained Syncope

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
Among patients with recurrent unexplained syncope and no prior AF, LV diastolic dysfunction quantified by the HFA‐PEFF score predicts sick sinus syndrome and atrial fibrillation. ABSTRACT Background Atrial fibrillation (AF) and sick sinus syndrome (SSS) frequently coexist and may share common atrial structural and electrophysiological remodeling ...
