Simultaneous dual AV node antegrade conduction (2 for 1) and lower common pathway (2–1) block illustrate AVNRT physiology

Indian Pacing and Electrophysiology Journal, 2020
We report a rare case of spontaneous initiation of Atrioventricular nodal reentry tachycardia (AVNRT) via 2 for 1 phenomenon, into a 2:1 AV block due to lower common pathway block and finally transition to 1:1 tachycardia.

Efficacy and safety of zero-fluoroscopy approach for ablation of atrioventricular nodal reentry tachycardia: experience from more than 1000 cases

Journal of interventional cardiac electrophysiology, 2022
Radiofrequency catheter ablation (RFCA) of the slow pathway in atrioventricular nodal reentry tachycardia (AVNRT) is associated with high efficacy and low risk of total perioperative or late atrioventricular block.

Long‐term follow‐up in preschool children after radiofrequency catheter ablation of arrhythmias

Journal of Arrhythmia, 2023
Background Radiofrequency ablation (RFA) is the standard method of treatment for tachyarrhythmias in school children, and it leads to complete recovery in children without structural heart disease. However, RFA in young children is limited by the risk of

Coronary sinus cannulation predicts atrioventricular nodal reentry as mechanism of supraventricular tachycardia

Indian Pacing and Electrophysiology Journal, 2019
Introduction: Common clinical teaching, for invasive electrophysiology, is that if the first year fellow cannulates the coronary sinus (CS) in his first attempt, the arrhythmia is more likely to be atrioventricular nodal reentry tachycardia (AVNRT). This

Association between the geographic region and the risk of familial atrioventricular nodal reentry tachycardia in the Polish population.

Polish Archives of Internal Medicine, 2021
INTRODUCTION Atrioventricular nodal reentry tachycardia (AVNRT) is one of the most common regular supraventricular arrhythmia referred for catheter ablation (CA).

Radiofrequency catheter ablation in infants and children

SA Heart Journal, 2017
Background: Diagnosis and treatment of paediatric arrhythmias remain challenging. Antiarrhythmic - drugs beta-blockers, class Ic and class III drugs, were the only treatment available for many years. Radiofrequency catheter ablation (RFCA) was introduced

New Insights into Reentry Circuits from Mapping and Ablation of Atrioventricular Nodal Reentrant Tachycardia [PDF]

, 2012
Atrioventricular nodal reentrant tachycardia (AVNRT) is a very common cardiac arrhythmia and is due to reentry within the region of the atrioventricular junction.

Sex-related differences in patients undergoing radiofrequency ablation of atrioventricular nodal reentrant tachycardia [PDF]

, 2020
Background: Atrioventricular nodal reentry tachycardia (AVNRT) is the most common paroxysmal supraventricular tachycardia. The relatively ineffective antiarrhythmic drugs and the predominant young age makes the catheter ablation the therapy of choice in ...

Prevention of Atrioventricular Block During Radiofrequency Ablation by Pace Mapping of Koch’s Triangle [PDF]

Journal of Tehran University Heart Center, 2008
Background: Complete atrioventricular block (AV block) is a serious complication of slow pathway ablation therapy in the treatment of atrioventricular nodal re-entrant tachycardia (AVNRT).
