Atrioventricular Nodal Reentry Tachycardia with Multiple AH Jumps:

Pacing and Clinical Electrophysiology, 2003
This article describes the additional use of incremental atrial burst pacing (A1A1) and double atrial extrastimulation with a predefined fast pathway conducted A2 (A1A2A3), rather than single atrial extrastimulation (A1A2) only, to characterize typical atrioventricular nodal reentrant tachycardia (AVNRT).

Characteristics, management, and midterm outcome in infants with atrioventricular nodal reentry tachycardia

The American Journal of Cardiology, 1998
Atrioventricular nodal reentry is a commonly recognized mechanism of supraventricular tachycardia (SVT) in adults, but is only rarely documented in the first year of life. The aim of this study was to elucidate characteristics, management, and outcome in infants with atrioventricular nodal reentrant tachycardia (AVNRT).

The electrophysiologic characteristics of atrioventricular nodal reentry tachycardia with eccentric retrograde activation

International Journal of Cardiology, 2007
The occurrence of eccentric retrograde atrial activation has been demonstrated to be from 6 to 8% in patients with atrioventricular nodal reentrant tachycardia (AVNRT) by several previous reports. However, most of those reports were limited by the absence of coronary sinus venography to confirm if the retrograde activation was truly left sided.

Evolving concepts in radiofrequency catheter ablation of atrioventricular nodal reentry tachycardia

American Heart Journal, 1994
Our results and those of others (Table I) suggest that both anatomic and electrogram (potential) approaches are highly successful in eliminating AVNRT. The use of slow-pathway potentials appears to minimize lesion delivery and to be associated with a very small likelihood of complete AV block.

Radiofrequency Modification for Inducible and Suspected Pediatric Atrioventricular Nodal Reentry Tachycardia

Journal of Interventional Cardiac Electrophysiology, 2005
AV Node Reentry Tachycardia (AVNRT) is the second most common supraventricular tachycardia (SVT) undergoing pediatric radiofrequency ablation behind accessory pathway reentry tachycardias. AVNRT can be difficult to induce during electrophysiology study (EPS) and dual atrioventricular nodal (AVN) pathways physiology may not be demonstrated in young ...

Entrainment to Distinguish Orthodromic Reciprocating Tachycardia from Atrioventricular Nodal Reentry Tachycardia in Children

Pacing and Clinical Electrophysiology, 2010
Studies in adults suggest that after entrainment from the right ventricle, a post-pacing interval (PPI) minus tachycardia cycle length (TCL), when corrected for atrioventricular node delay (cPPI-TCL), is useful to distinguish atrioventricular nodal reentry tachycardia (AVNRT) from orthodromic reciprocating tachycardia (ORT), but this has not been ...

P6560Delayed ablation of atrioventricular nodal reentry tachycardia as a risk factor for future atrial fibrillation

European Heart Journal, 2019
Atrioventricular nodal reentry tachycardia (AVNRT) is the most common type of supraventricular tachycardia. Most of the patients experience recurrent symptoms for years before electrocardiographic documentation and AVNRT ablation.

Differential entrainment distinguishes atrioventricular nodal reentry tachycardia from atrioventricular reentrant tachycardia.

Pacing and clinical electrophysiology : PACE, 2011
Entrainment from the right ventricular (RV) apex and the base has been used to distinguish atrioventricular reentrant tachycardia (AVRT) from atrioventricular nodal reentry tachycardia (AVNRT). The difference in the entrainment response from the RV apex in comparison with the RV base has not been tested.Fifty-nine consecutive patients referred for ...

[Incessant supraventricular tachycardia due to upper atrioventricular nodal reentry].

Journal of cardiology, 1989
Three patients with recurrent supraventricular tachycardia were presented. Atrial cycle length unchanged during the tachycardia with antegrade Wenckebach AH block was observed. When AH block occurred during tachycardia, the first AH interval was shorter than the subsequent one.
