A conflict of evidence: AVNRT or junctional tachycardia?

Heart Rhythm, 2013
Case presentation A 49-year-old woman who had previously undergone atrioventricular node (AVN) slow pathway cryoablation for typical AVN reentry tachycardia (AVNRT) presented with recurrent supraventricular tachycardia (SVT). During a transvenous electrophysiologic study, the SVT was reproducibly inducible with programmed atrial stimulation that ...

Cryoablation of AVNRT When Sustained Tachycardia Cannot be Induced

PACE - Pacing and Clinical Electrophysiology, 2013
BackgroundInducibility of sustained tachycardia is preferred prior to cryoablation for atrioventricular nodal reentrant tachycardia (AVNRT).MethodThe Pediatric Electrophysiology Database of a single institution was retrospectively reviewed for patients with clinical sustained (≥30 seconds of symptoms) AVNRT documented by noninvasive means who underwent

Persistence of Palpitations After Slow Pathway Modification for AVNRT in Young People

Pediatric Cardiology, 2021
Symptoms are the most common indication for ablation in children with atrioventricular nodal reentrant tachycardia (AVNRT). After the procedure, patients may continue to report palpitations.

Characteristics of Slow Pathway Conduction After Successful AVNRT Ablation

Journal of Cardiovascular Electrophysiology, 2006
Background: AV node slow pathway conduction can persist following successful ablation for AV node reentrant tachycardia (AVNRT). We hypothesized that careful examination of AV nodal conduction curves before and after effective AVNRT ablation in patients ...

Zero-fluoro AVNRT ablation

European Heart Journal, 2022
Abstract Background Atrioventricular-nodal reentry tachycardia (AVNRT) is a common supraventricular tachycardia, particularly in younger patients. First-line therapy in symptomatic patients is radiofrequency catheter ablation (RFCA).

How to Approach Difficult Cases of AVNRT

Current Treatment Options in Cardiovascular Medicine, 2017
Our approach to the ablation of atrioventricular nodal reciprocating tachycardia (AVNRT), the most common supraventricular tachycardia, is as follows: We first attempt ablation in the right atrial posteroseptum anterior to the coronary sinus ostium with a 4-mm non-irrigated tip catheter.

Leaping to Diagnosis: The Frog Sign as a Key Clue in AVNRT

Clinical Case Reports (discontinued)
The “frog sign,” characterized by prominent cannon A waves, is a critical diagnostic clue for AV‐nodal reentrant tachycardia (AVNRT). It was confirmed through electrophysiological study and was successfully treated with radiofrequency ...

Typical AVNRT—An Update on Mechanisms and Therapy

Cardiac Electrophysiology Review, 2002
Typical atrioventricular reentrant tachycardia (AVNRT) is the most common paroxysmal supraventricular tachycardia among adults, and accounts for considerable morbidity. The concept of dual pathway physiology remains useful, although this physiology likely results from the functional properties of anisotropic tissue within the triangle of Koch, rather ...
