Parasympathetic Tone Selectively Modulates Electrogram Fragmentation and Spectral Properties in Right Atrial Ganglionated Plexi

Journal of Arrhythmia, Volume 42, Issue 4, August 2026.
Electrogram fragmentation and spectral EGMs features in GPs area are selectively modulated by parasympathetic tone, as demonstrated by high‐density right atrial mapping before and after vagal blockade. EGMs, bipolar atrial electrograms; GPs, ganglionated plexi; RA, right atrium.

Electrocardiographic Predictors of Cardiac Reverse Remodeling After Left Bundle Branch Area Pacing in Atrioventricular Block: Emphasis on Post‐Pacing QRS Duration

Journal of Arrhythmia, Volume 42, Issue 4, August 2026.
In patients with atrioventricular block undergoing left bundle branch area pacing, shorter post‐pacing QRS duration was associated with cardiac reverse remodeling. Post‐pacing QRS duration may represent a simple and clinically applicable electrocardiographic marker for identifying patients more likely to achieve reverse remodeling.

The Japanese Catheter Ablation Registry (J‐AB): Annual Report in 2024

Journal of Arrhythmia, Volume 42, Issue 4, August 2026.
Analysis of 112 151 catheter ablation procedures from the 2024 Japanese Catheter Ablation (J‐AB) Registry demonstrated consistently low acute complication rates, with a slight reduction from 2023, confirming the safety of contemporary catheter ablation practice in Japan.

Association Between Inferior Vena Cava Location and the Number of Deployments of a Leadless Pacemaker

Journal of Arrhythmia, Volume 42, Issue 4, August 2026.
This study evaluated the impact of inferior vena cava (IVC) location, assessed by preoperative CT, on leadless pacemaker implantation in 96 patients. Left‐sided IVC group was significantly associated with a higher risk of multiple deployments compared to Right‐sided IVC group (67% vs. 36%, p = 0.02).

Artificial Intelligence Techniques in Cardiac Neuromodulation: Mechanisms, Applications, and Pathways to Clinical Translation

Journal of Arrhythmia, Volume 42, Issue 4, August 2026.
Artificial intelligence could improve patient selection, stimulation control, and response monitoring in cardiac neuromodulation, yet direct clinical evidence remains scarce. We map available techniques onto these three challenges and argue that safe, adaptive closed‐loop control and established therapy efficacy are prerequisites for translation ...

A novel selective stabilizer of the ryanodine receptor 2 prevents stress‐induced ventricular arrhythmias without impairing cardiac function

British Journal of Pharmacology, Volume 183, Issue 15, Page 4321-4343, August 2026.
Abstract Background and Purpose Aberrant activation of type 2 ryanodine receptors (RyR2) causes lethal arrhythmias, such as catecholaminergic polymorphic ventricular tachycardia (CPVT). Developing drugs that suppress RyR2 hyperactivation may be key to novel arrhythmia treatments.

Diltiazem N‐oxide, a novel ischaemia‐activated prodrug, prevents ischaemia‐induced ventricular fibrillation without off‐target adverse effects

British Journal of Pharmacology, Volume 183, Issue 16, Page 4646-4662, August 2026.
Abstract Background and Purpose Ventricular fibrillation (VF) in coronary heart disease accounts for up to 70% of sudden cardiac death. We examined whether diltiazem N‐oxide (DNO) has ischaemia‐selective antiarrhythmic activity. Experimental Approach Randomised and blinded experiments were performed in rat isolated hearts and in anaesthetised rats to ...
