Distinctive characteristics of His bundle potentials in patients with atrioventricular nodal reentrant tachycardia

Cardiology Journal, 2023
BACKGROUND: His bundle (HB) potentials vary in amplitude and duration in patients with and without slow pathways. The aim of this study was to determine the characteristics of HB potentials and to elucidate whether they can provide clues for ...

A Case of Junctional Ectopic Tachycardia and Complete Atrioventricular Block After Transcatheter Aortic Valve Replacement

Annals of Noninvasive Electrocardiology, Volume 30, Issue 6, November 2025.
This case highlights junctional ectopic tachycardia (JET) and complete atrioventricular (AV) block after transcatheter aortic valve replacement (TAVR). JET after TAVR may be associated with AV block, potentially requiring rate control with medication and pacemaker implantation.

Rate-dependent and antiarrhythmic reentrant tachycardia (AVNRT) effects of simvastatin in isolated rabbit atrioventricular nodal model [PDF]

, 2010
Background and purpose: Several previous studies have shown the direct and indirect effects of statins on supraventricular and ventricular arrhythmia. The purpose of the present study is to determine (1) whether Simvastatin modifies the rate-dependent ...

Long‐Term Follow‐Up of Inducible Bundle Branch Reentrant Ventricular Tachycardia in Patients Without Structural Heart Disease: Beyond the Electrophysiology Laboratory

Journal of Cardiovascular Electrophysiology, Volume 36, Issue 9, Page 2140-2150, September 2025.
ABSTRACT Background Bundle branch reentrant ventricular tachycardia (BBR‐VT) is a rare form of VT occurring in patients with structural heart disease (SHD). Rarely, it can also occur in the absence of SHD. Understanding its clinical and electrophysiologic (EP) properties and outcomes post‐catheter ablation (CA) is crucial. Objective We present a series

Extra‐cardiac vagal stimulation: Clinical utility of a novel diagnostic and therapeutic tool in supraventricular tachycardia

Journal of Arrhythmia, Volume 41, Issue 4, August 2025.
Extracardiac vagal stimulation (ECVS) is a novel, safe tool inducing controlled AV/VA block. It assists SVT differential diagnosis, pathway unmasking, and ablation endpoint confirmation, adding value to EP procedures for supraventricular tachycardias.

Role of slow pathway after nodal fast pathway ablation on the basic and rate-dependent properties of the isolated rabbit atrioventricular node [PDF]

, 2009
Introduction: The aim of this study was to obtain new insights into the possible relations between functional properties of slow concealed pathway and rate-dependent properties of the AV-node.

Cx43 and Dual-Pathway Electrophysiology of the Atrioventricular Node and Atrioventricular Nodal Reentry [PDF]

Circulation Research, 2003
Fluorescent imaging has revealed that posterior nodal extensions provide the anatomical substrate for the dual-pathway electrophysiology of the atrioventricular (AV) node during normal conduction and reentry. The reentry can be intranodal, or as well as the posterior nodal extensions, it can involve an endocardial layer of atrial/atrial-nodal (A/AN ...

Vergleichende Langzeitbeobachtung unterschiedlicher Patientengruppen mit implantierten, automatischen Schrittmacher/Defibrillatoren [PDF]

, 2003
In dieser Arbeit wurden 210 Patienten konsekutiv mit einem ICD versorgt und über 10 Jahre u.a. bezüglich der Schockabgaben und der Mortatlität untersucht. Dabei wurden 2 unterschiedliche Gruppen gebildet.
