结局指标
主要结局
Three-month follow-up success rate after surgery
时间窗: Three months after surgery
Postoperative 3-month treatment success rate: Specifically refers to the proportion of participants who, during the 3-month follow-up period post-surgery (after the washout period), did not experience any episodes of atrial fibrillation/atrial flutter/atrial tachycardia lasting ≥30 seconds, as confirmed by electrocardiogram (ECG), Holter monitoring, or equivalent rhythm monitoring methods (including single-lead ECG), without the use of Class I or Class III antiarrhythmic drugs, relative to the total number of enrolled participants.
次要结局
- Immediate ablation success rate(On the 1 day of the surgery)
