Sleep Apnea and Paroxysmal Atrial Fibrillation: Diurnal Patterning of Autonomic Dysfunction and Influence of CPAP Therapy

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
Autonomic dysfunction in sleep apnea shows diurnal variation, with stronger associations between SDB severity and HRV during wakefulness than sleep. CPAP therapy induces complex, state‐dependent changes in HRV, suggesting that daytime autonomic alterations may better reflect sustained cardiovascular risk in patients with paroxysmal atrial fibrillation.

Efficacy and Safety of Catheter Ablation in Very Elderly Patients With Atrial Fibrillation: Short‐ To Mid‐Term Outcomes From a Multicenter Study

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
Patients aged ≥ 80 years with atrial fibrillation underwent catheter ablation. At 2 years, the recurrence‐free survival rate was 85.8% in paroxysmal AF and 63.6% in persistent AF (p = 0.024), and periprocedural complications occurred in 12.0%, including severe complications in 3.3%.

Feasibility and Safety of High‐Power Settings for Electrical Isolation of the Superior Vena Cava Using a Catheter Capable of Local Impedance and Contact Force Monitoring

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
High‐power superior vena cava isolation using a contact force– and local impedance–sensing catheter achieved safe and consistent first‐pass isolation. Local impedance decreased more rapidly than generator impedance, accurately reflecting effective lesion formation and enabling reliable real‐time assessment in thin SVC myocardium.

Interlesion Time as a Key Metric of Procedural Proficiency in Atrial Fibrillation Ablation: From Fellow to Attending

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
Attending EPs performed ablation with shorter ILT, which likely contributed to more efficient procedures and reduced overall ablation time. ABSTRACT Introduction Pulmonary vein isolation (PVI) is a cornerstone of atrial fibrillation (AF) ablation. Unlike balloon‐based or pulsed field ablation, radiofrequency ablation requires precise catheter control ...

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.
