Resistant to Ablation, Responsive to Hydroquinidine: Precision Medicine Guides Recovery in MEPPC Syndrome Cardiomyopathy

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
We report a case of MEPPC syndrome presenting with severe dilated cardiomyopathy due to a pathogenic SCN5A p.Arg814Trp variant. Genetic diagnosis enabled precision pharmacotherapy with hydroquinidine, which suppressed multifocal Purkinje‐origin ectopy resistant to catheter ablation and led to marked improvement in left ventricular function.

Increased baseline ECG R-R dispersion predicts improvement in systolic function after atrial fibrillation ablation. [PDF]

, 2019
BackgroundAtrial fibrillation (AF) is associated with left ventricular (LV) systolic dysfunction which may improve after AF ablation. We hypothesised that increased ventricular irregularity, as measured by R-R dispersion on the baseline ECG, would ...

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%.

Channel and Spatial Parallel Attention for ECG‐Based Prediction of Concealed Accessory Pathways and Atrioventricular Nodal Reentry Tachycardia

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
CSPANet, a deep learning model with channel and spatial parallel attention, distinguishes concealed accessory pathways and atrioventricular nodal reentry tachycardia from sinus‐rhythm ECGs with 92.6% accuracy. This novel approach facilitates optimized ablation planning and enhances procedural safety, addressing a key diagnostic gap in arrhythmia ...

Impact of Pericardial Fat on Intracardiac Atrial Impedance and Generator Impedance

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
Intracardiac atrial impedance (IAI) was associated with pericardial fat volume, serum sodium levels, and hemoglobin concentrations, but not with body mass index. IAI was also an independent determinant of generator impedance. These findings suggest that IAI may serve as a real‐time indicator for optimizing ablation strategies based on patient‐specific ...

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.

Short- and long-term experience in pulmonary vein segmental ostial ablation for paroxysmal atrial fibrillation* [PDF]

Introduction: Segmental ostial pulmonary vein isolation (PVI) is considered a potentially curative therapeutic approach in the treatment of paroxysmal atrial fibrillation (PAF).

Efficacy of a Novel Ablation Index Algorithm for Cavotricuspid Isthmus Ablation Using a Flexible‐Tip Ablation Catheter

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
AutoMark Index (AI) is a novel ablation algorithm that combines contact force, radiofrequency current, and application to provide real‐time lesion formation. AI‐guided CTI ablation protocol is efficient in shortening RF duration for acute bidirectional CTI block and CTI procedure time compared to the conventional 40 W ablation protocol.

Clinical and Genetic Characterization of Inherited NPRL3 Splice Variants in Two Patients With Epilepsy

Molecular Genetics &Genomic Medicine, Volume 14, Issue 6, June 2026.
This study identifies two novel inherited NPRL3 splice variants in Chinese pediatric patients with focal epilepsy, revealing significant genetic heterogeneity, incomplete penetrance, and phenotypic variability that underscores the importance of tailored antiepileptic management.
