atrial fibrillation
Conditions
Interventions
Low risk of recurrence group:Using conventional ablation strategies (at the vestibular site of the pulmonary vein)
High risk of recurrence group:The ablation index increased by 10-20 when the conventional pathway of circumferential pulmonary vein ablation deviated 2-4mm from the atrial side.
