Overview

Accelerated junctional rhythm's low specificity advises against sole reliance for confirming success; leaves open identification of more specific AVNRT ablation markers.

Structured PICO

Does an accelerated junctional rhythm predict the success of slow AV nodal pathway ablation in patients with AVNRT?

P
Population
Patients with typical slow-fast AVNRT undergoing slow AV nodal pathway ablation
I
Intervention
Radiofrequency (RF) ablation of the antegrade slow AV nodal pathway
O
Outcome
Accelerated junctional rhythm as a marker for successful slow pathway ablationsurrogate

While highly sensitive, accelerated junctional rhythm has low specificity for predicting successful slow AV nodal pathway ablation in AVNRT.

Cite This Study

G. Neal Kay (2021) conducted a review in Atrioventricular nodal reentrant tachycardia (AVNRT). Slow AV nodal pathway ablation was evaluated. Accelerated junctional rhythm during slow AV nodal pathway ablation for AVNRT has a high sensitivity (98%) but low specificity (45%) for predicting successful ablation.
