Importance of Sinus Rhythm as Endpoint of Persistent Atrial Fibrillation Ablation

Endpoint of Persistent AF Ablation. Background: The endpoint of persistent atrial fibrillation (AF) ablation is still a matter of debate. The purpose of this study was to evaluate if sinus rhythm (SR) as endpoint of persistent AF ablation has a better long‐term outcome compared to atrial tachycardia (AT) or AF at the end of the procedure.
