Beat‐to‐beat variability of ventricular repolarization reveals sex‐specific instability and proarrhythmic risk

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A mechanistic framework linking sex‐dependent dynamical instability to proarrhythmic risk. Sex‐specific human ventricular models show that upstream modulators, including biological sex, hormones, drugs and heart disease, promote steeper APD restitution in female than male and enhance dynamical instability.

Opening closed inward rectifier potassium channel doors

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 10, Page 2197-2218, May 2026.
Inwardly rectifying potassium (KIR) channels are essential regulators of membrane potential in excitable and non‐excitable tissues. Although KIR channels exhibit a biophysical preference for potassium influx due to voltage‐dependent block of outward current by polyamines and Mg2+, under physiological conditions, they predominantly mediate K+ efflux ...

Comparative effectiveness and safety of oral anticoagulants in patients with atrial fibrillation using antiarrhythmic drugs: An international cohort study

open access: yesBritish Journal of Clinical Pharmacology, Volume 92, Issue 4, Page 1177-1185, April 2026.
Aim Our international cohort study assessed the comparative effectiveness and safety of direct oral anticoagulants (DOACs) and vitamin K antagonists (VKAs) among patients with non‐valvular atrial fibrillation (NVAF) using antiarrhythmic drugs. Methods Using the United Kingdom's (UK's) Clinical Practice Research Datalink Aurum and Québec claims data, we

Catheter Ablation for Frequent Premature Ventricular Contractions or Paroxysmal Supraventricular Tachycardia With Vagal Bradycardia: A New Clinical Application of Superior Vena Cava–Aorta Ganglionated Plexus Modification

open access: yesClinical Cardiology, Volume 49, Issue 4, April 2026.
This study demonstrates that combined RFCA and right atrial Ao‐SVC GP ablation provides a one‐stop, innovative solution for patients with vagal bradycardia and concomitant tachyarrhythmias, significantly improving symptoms and reducing syncope. ABSTRACT Background Frequent premature ventricular contractions (PVCs) or paroxysmal supraventricular ...

Brugada-Phenocopy Induced by Propafenone Overdose and Successful Treatment: A Case Report

open access: yesBalkan Medical Journal, 2017
Background: Brugada syndrome is an inherited arrhythmogenic disease that may cause sudden cardiac death due to ventricular fibrillation in young adults. Brugada syndrome caused by propafenone intoxication has been noted rarely in the literature.

Kuwait Atrial Fibrillation Management Analysis—Insights From a Tertiary Center in Kuwait

open access: yesJournal of Arrhythmia, Volume 42, Issue 2, April 2026.
Among patients with non‐valvular AF, rhythm control (RC) was pursued in 28.9%. RC was pursued for younger patients and those followed in electrophysiology clinics (33% vs. 5%, p < 0.001). 11.6% of patients received an underdosed DOAC. RC was underutilized in our study, falling short of international benchmarks and guideline recommendations.

The Evolving Role of Ivabradine for Focal Atrial Tachycardia: A Systematic Review

open access: yesJournal of Arrhythmia, Volume 42, Issue 2, April 2026.
Overview of the evolving role of ivabradine in focal atrial tachycardia (FAT), highlighting its HCN‐mediated mechanism, features of ivabradine‐sensitive FAT, hypothesized predictors of response, special populations requiring special considerations, and potential adverse effects.

Liver disease in management and outcomes of European and Asian patients with atrial fibrillation: A report from two observational prospective registries

open access: yesEuropean Journal of Clinical Investigation, Volume 56, Issue 4, April 2026.
In this large European–Asian cohort of patients with atrial fibrillation, liver disease was linked to lower oral anticoagulant use—particularly in Europe—and to higher risks of mortality and cardiovascular events. These findings highlight the adverse impact of liver disease, especially when oral anticoagulation is withheld.

Propafenone and amiodarone efficacy in paroxysmal atrial fibrillation treatment

open access: yesРоссийский кардиологический журнал, 2006
To assess antiarrhythmic efficacy of propafenone and amiodarone in paroxysmal atrial fibrillation (AF) treatment, 204 patients (125 males, 79 females, aged 57-72 years) with various stages of heart failure (HF) were examined.

Incremental Value of NT‐proBNP Over HCM‐AF Score in Risk Stratification for Atrial Fibrillation in Patients With Hypertrophic Cardiomyopathy

open access: yesClinical Cardiology, Volume 49, Issue 3, March 2026.
In Asian patients with hypertrophic cardiomyopathy, integrating NT‐proBNP with the clinical HCM‐AF score provides significant incremental prognostic value. This combined multiparametric assessment enhances the predictive accuracy for new‐onset atrial fibrillation, enabling more precise risk stratification and targeted clinical management.
