Overview

May aid real-time confirmation during AVNRT ablation; leaves open need for prospective validation before practice change.

Structured PICO

Do junctional rhythm characteristics and anatomic ablation site predict successful slow pathway radiofrequency ablation in patients with AVNRT?

P
Population
39 patients undergoing radiofrequency ablation of the slow pathway for atrioventricular nodal reentrant tachycardia (AVNRT)
I
Intervention
Radiofrequency ablation of the slow pathway across different anatomic zones (low posterior septum to distal His-bundle recording)
C
Comparator
Comparison between different ablation sites (mid-septal vs posterior) and successful vs unsuccessful applications
O
Outcome
Successful slow pathway ablation and characteristics of junctional rhythm during RF applicationssurrogate

Junctional rhythm characteristics, specifically early onset combined with a mid-septal ablation site, are highly predictive of successful slow pathway ablation in AVNRT.
