BRASH Syndrome

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT BRASH syndrome is a life‐threatening clinical entity characterized by Bradycardia, Renal failure, Atrioventricular (AV) blockade, Shock, and Hyperkalemia. This syndrome is often triggered in patients on AV nodal blocking agents who develop acute kidney injury, leading to a “vicious cycle” of worsening bradycardia and renal dysfunction.

A Case Report of PR Interval Prolongation Caused by Amlodipine

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Amlodipine is a widely used dihydropyridine calcium channel blocker. Its effects on the cardiac conduction system, especially PR interval prolongation, are rare but clinically important. We report a 25‐year‐old healthy male subject in a clinical trial with baseline first‐degree atrioventricular block (PR interval 230 ms).

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.

Para‐Hisian Extra Pacing Enables Unmasking of Hidden Slow Retrograde Conduction

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
In the presence of dual retrograde pathways, conventional Para‐Hisian pacing may fail to reveal the slow pathway, likely due to masking by fast retrograde conduction. In such cases, Para‐Hisian extra pacing—combining programmed right ventricular stimulation with differential His bundle capture—enables assessment of the slow retrograde conduction.

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 ...

Premature Beats With QRS Morphology Identical to Sinus Rhythm: What Is the Mechanism

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
This case illustrates a rare presentation of premature junctional contractions arising from the atrioventricular nodal region, particularly the slow pathway, mediated by non‐sustained reentrant activity. This mechanism does not result in sustained tachycardia but instead produces isolated echo beats.

Familial sick sinus syndrome in two siblings

The Turkish Journal of Pediatrics, 1993
Two siblings with sinus node disease are presented. The patients were severely affected and required permanent pacing. A cardiac electrophysiologic study was conducted in Case 2, which revealed an atrioventricular conduction disturbance in ...

Adenosine‐Sensitive Focal Atrial Tachycardia Late After Atriopulmonary Connection Fontan Procedure: A Case Report

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
We describe a case of adenosine‐sensitive focal atrial tachycardia (AT) in a patient late after atriopulmonary connection (APC) Fontan procedure. Radiofrequency application successfully abolished the AT; meanwhile, conversion to total cavopulmonary connection (TCPC) and/or Maze procedure may fail to suppress the AT because the origin was crista ...

Mahaim Fiber Accelerated Automaticity and Clues to a Mahaim Fiber Being Morphologically an Ectopic or a Split AV Node

Indian Pacing and Electrophysiology Journal, 2010
Mahaim Fiber tachycardia characteristically causes a wide QRS tachycardia with left bundle branch morphology and left axis deviation, especially in young patients, having no structural heart disease.

Atrial Leadless Pacemaker Embolization to the Left Common Iliac Vein With Successful Retrieval: A Case Report

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
A rare extracardiac complication in which a dislodged atrial leadless pacemaker migrated retrogradely to the left common iliac vein. This case highlights the role of venous anatomy in implantation difficulty and demonstrates successful device retrieval using a preventive strategy.
