The study investigates the impact of having sinus rhythm (SR) at the time of catheter ablation (CA) on long-term outcomes for patients with persistent atrial fibrillation (PersAF).
Results show that patients who presented in SR had better freedom from atrial arrhythmias (AAs) after the procedure compared to those who presented in atrial fibrillation (AF).
The findings suggest that achieving SR before ablation can improve overall arrhythmia outcomes and prolong the time until recurrent AF.
