ICD discrimination of SVT versus VT with 1:1 V-A conduction: A review of the literature

Indian Pacing and Electrophysiology Journal, 2015
Inappropriate ICD shocks are associated with increased mortality. They also impair patients' quality of life, increase hospitalizations, and raise health-care costs. Nearly 80% of inappropriate ICD shocks are caused by supraventricular tachycardia.

Interesting response to ventricular overdrive pacing during regular narrow QRS tachycardia. What is the mechanism?

Indian Pacing and Electrophysiology Journal, 2020
33 year old gentleman has undergone an electrophysiology study for recurrent paroxysmal palpitation. During one of the episodes of palpitation a regular narrow QRS tachycardia was documented which has terminated with intravenous adenosine.

Zero Fluoroscopy Ablation of Arrhythmias in Patients With Congenital Heart Disease

Journal of Arrhythmia, Volume 41, Issue 6, December 2025.
Zero‐fluoroscopy radiofrequency ablation using 3D electroanatomic mapping was performed in 42 patients with mild, moderate, or great complexity congenital heart disease. Acute success was 100%, with no complications and minimal recurrence over 48 months. This approach eliminates radiation exposure while maintaining safety and efficacy across select yet

Atrioventricular nodal reentry. Clinical, electrophysiological, and therapeutic considerations. [PDF]

Circulation, 1993
BACKGROUND Atrioventricular (AV) nodal reentry is a relatively common cause of regular, narrow QRS tachycardia. The underlying basis for this arrhythmia is functional (and anatomic) duality of pathways in the region of the AV node, although the exact boundaries of the reentrant circuit have not been convincingly defined.

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.

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

Influence of Atrioventricular Nodal Reentrant Tachycardia Ablation on Right to Left Inter-atrial Conduction [PDF]

, 2005
Background: Radiofrequency (RF) catheter ablation is the procedure of choice for the potential cure of atrioventricular nodal reentrant tachycardia (AVNRT) with high success rates.

Differential responses of the septal ventricle and the atrial signals during ongoing entrainment: a method to differentiate orthodromic reciprocating tachycardia using septal accessory pathways from atypical atrioventricular nodal reentry [PDF]

, 2015
[EN]Differential diagnosis between tachycardia mediated by septal accessory pathways (AP) and atypical atrioventricular nodal reentry can be challenging. We hypothesized that an immediate versus delayed pace-related advancement of the atrial electrogram,

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.

A “drop” in the atrioventricular conduction curve and dual-pathway electrophysiology

Heart Rhythm O2
Background: Atrioventricular (AV) conduction time is rate-dependent. As the atrial coupling interval (A1A2) shortens, AV conduction time (A2H2) prolongs. Thus, the AV conduction curve, plotted using A1A2 vs A2H2, is usually “smooth” and “monotonic”.
