What researchers measure

Primary outcomes

  1. Clinical recurrence of atrial fibrillation (AF) after catheter ablation

    We defined recurrence of AF as any episode of AF or atrial tachycardia lasting longer than 30 sec. Any ECG documentation of AF recurrence after 3 months was diagnosed as clinical recurrence.

    Time frame: after 90 days of catheter ablation and thereafter
