Intracardiac ablation for atrioventricular nodal reentry tachycardia using a 6 mm distal electrode cryoablation catheter: Prospective, multicenter, North American study (ICY‐AVNRT STUDY)

Cardiovascular Electrophysiology, 2018
Radiofrequency (RF) ablation is effective for slow pathway ablation, but carries a risk of inadvertent AV block requiring permanent pacing. By comparison, cryoablation with a 4‐mm distal electrode catheter has not been reported to cause permanent AV ...

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

Experimentally created atrioventricular node reentrant tachycardia in the dog: Evidence of a brake system for nodal reentry in the anterior interatrial septum [PDF]

, 1993
Objectives. The purpose of the study was to investigate the hypothesis that nodal approaches of both anterior and posterior atrial input sites of the atrioventricular (AV) node contribute to part of the circuit of AV node reentrant tachycardia.

[Atrioventricular nodal reentry tachycardia in children].

Tidsskrift for den Norske laegeforening : tidsskrift for praktisk medicin, ny raekke, 2006
Atrioventricular nodal reentry tachycardia is a supraventricular tachycardia with a double nodal pathway between the atria and the ventricles located in the normal AV-node. It may cause a reentry circuit. Atrioventricular nodal reentry tachycardia is one of the most common supraventricular tachycardias in adulthood, but is seldom diagnosed in children--

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.

Curative surgery for atrioventricular junctional (“AV Nodal”) reentrant tachycardia [PDF]

, 1985
A new surgical approach was studied prospectively in 10 consecutive patients with atrioventricular (AV) junctional reentrant tachycardia. The aim was to abolish tachycardia yet preserve normal AV conduction.

A technique for the rapid diagnosis of atrial tachycardia in the electrophysiology laboratory [PDF]

, 1999
OBJECTIVEThe purpose of this study was to determine if the atrial response upon cessation of ventricular pacing associated with 1:1 ventriculoatrial conduction during paroxysmal supraventricular tachycardia is a useful diagnostic maneuver in the ...

Orthodromic Atrioventricular Reentry Bradycardia and Tachycardia Caused by an Accessory Pathway in Horses

Journal of Veterinary Internal Medicine, Volume 39, Issue 4, July/August 2025.
ABSTRACT Background Accessory pathways (APs) are muscular bundles directly connecting the atria and ventricles, bypassing the atrioventricular (AV) node‐His‐Purkinje system. Anterograde conduction along the AP results in ventricular preexcitation. A retrograde conducting AP allows ventriculo‐atrial (VA) conduction, creating a reentry circuit that ...

Assessment of the influence of radiofrequency catheter ablation of the slow pathway of the atrioventricular node on cardiac function in patients with atrioventricular nodal reentrant tachycardia: a speckle tracking echocardiography study

Türk Kardiyoloji Derneği Arşivi, 2014
Objectives: Typical atrioventricular nodal reentrant tachycardia (AVNRT) can be cured with slow pathway ablation. This study was designed to assess the alterations in atrial and ventricular functioning using speckle tracking echocardiography in ...
