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 ...

Inducible Atrioventricular Nodal Reentry Tachycardia in Infants with a History of Neonatal Orthodromic Reciprocating Tachycardia

Pacing and Clinical Electrophysiology, 2003
Atrioventricular nodal reentry tachycardia (AVNRT) is an uncommon mechanism of supraventricular tachycardia in neonates in whom orthodromic reciprocating tachycardia (ORT) predominates. We report three patients with structurally normal hearts who presented with neonatal ORT, documented by transesophageal electrophysiology studies at 2 to 3 weeks of ...

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 ...

Variable Effects of Adenosine on Retrograde Conduction in Patients with Atrioventricular Nodal Reentry Tachycardia

Pacing and Clinical Electrophysiology, 1998
Adenosine has been demonstrated to reliably produce transient block of atrioventricular nodal (AVN) conduction, and has been advocated as a method of differentiating retrograde conduction via the atrioventricular node from accessory pathway conduction. However, the response of retrograde AVN to adenosine in patients with typical atrioventricular nodal ...

Induction of atrioventricular nodal reentry tachycardia with intravenous adenosine.

Singapore medical journal, 2007
Adenosine, used to terminate paroxysmal supraventricular tachycardia (SVT), is often useful in understanding the mechanism of tachycardia. This case report describes induction of SVT with adenosine in a 36-year-old man presenting with recurrent palpitations.

[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.

[Catheter ablation of accessory pathways and atrioventricular nodal reentry tachycardia].

Zeitschrift fur Kardiologie, 2000
Radiofrequency current catheter ablation has gained acceptance as primary long-term therapy for patients with symptomatic accessory pathways and symptomatic atrioventricular nodal reentrant tachycardia (AVNRT) with frequent recurrences. In both arrhythmias, curative treatment is possible in more than 90% of cases at a low complication rate although an ...
