Stokes–Adams Syncope and Ventricular Standstill

open access: yesJournal of Arrhythmia, Volume 42, Issue 4, August 2026.
Stokes–Adams syncope has various etiologies including atrioventricular conduction delays, ischemia, or vagal mechanisms. Careful EKG analysis including serial EKGs, may help identify contributory mechanisms to the etiology of syncope, even after permanent pacemaker implantation.

Midterm Efficacy of SubcutAneous Implantable CardioVErter‐Defibrillator in ≤ 18 Year‐Old CHILDREN (SAVE CHILDREN‐II Registry)

open access: yesJournal of Arrhythmia, Volume 42, Issue 4, August 2026.
S‐ICD therapy demonstrated favorable mid‐term safety and efficacy in pediatric patients, with durable sensing performance and a low incidence of device‐related infection. ABSTRACT Background The subcutaneous implantable cardioverter‐defibrillator (S‐ICD) avoids transvenous leads and is a promising option for sudden cardiac death (SCD) prevention in ...

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

open access: yesJournal 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.

High‐Density Electroanatomical Mapping of Alternating Short‐ and Long‐RP Orthodromic Tachycardia With Identical Atrial Breakthrough

open access: yesJournal of Arrhythmia, Volume 42, Issue 4, August 2026.
High‐density electroanatomical mapping during orthodromic tachycardia with alternating short‐ and long‐VA conduction patterns demonstrated an identical earliest atrial breakthrough. Although this supports a common atrial insertion, it cannot distinguish functional longitudinal dissociation within a single accessory pathway from closely adjacent ...

Pre‐Excited Atrial Fibrillation Degenerating Into Ventricular Fibrillation Captured by an Automated External Defibrillator

open access: yesJournal of Arrhythmia, Volume 42, Issue 4, August 2026.
An automated external defibrillator (AED) captured the real‐time transition from pre‐excited atrial fibrillation to ventricular fibrillation in a previously undiagnosed patient with WPW syndrome. This case highlights the malignant potential of rapidly conducting accessory pathways.

Anatomical Challenges During Left‐Sided Accessory Pathway Ablation in a Patient With Pectus Carinatum

open access: yesJournal of Arrhythmia, Volume 42, Issue 4, August 2026.
In a patient presenting with Wolff‐Parkinson‐White syndrome and pectus carinatum, cardiac rotation rendered conventional RAO and LAO views unreliable during left‐sided accessory pathway ablation. Customized fluoroscopic views with caudal angulation allowed for successful ablation, supporting pre‐procedural CT imaging to plan for patient specific ...

Belhassen Syndrome in Teenager Originating from Left Anterior Fascicle

open access: yesJournal of Cardiac Arrhythmias, 2020
A 16-year-old female patient was hospitalized due to narrow QRS tachycardia suggestive of fascicular ventricular tachycardia. Initially, the differential diagnosis with supraventricular tachycardia can be challenging.

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

open access: yesBritish 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 ...

Acute Myocarditis: From Pathophysiology to Risk‐Stratified Management—A Clinical Review

open access: yesEuropean Journal of Clinical Investigation, Volume 56, Issue 8, August 2026.
Stepwise approach to patients with suspected acute myocarditis, integrating the 2024 American College of Cardiology (ACC) four‐stage classification (Stages A–D) and the 2025 European Society of Cardiology (ESC) inflammatory myopericardial syndrome (IMPS) framework. Step 1 (Initial Assessment): clinical presentation, first‐line investigations (ECG, high‐
