Atrial fibrillation (AF) recurrence is common in the 3-month blanking-period after catheter ablation, during which electrical cardioversion (ECV) is usually performed to restore sinus rhythm. Whether ECV can affect the clinical outcome of post-ablation AF patients is inconsistent, however. We aimed to explore the 1-year effect of ECV on AF recurrence and rehospitalization in patients experienced recurrence within 3-month after AF catheter ablation.

电复律对心房颤动导管消融术后早期复发患者1年预后的影响

心房颤动 (AF) 复发常见于导管消融后 3 个月的空白期，在此期间通常进行电复律 (ECV) 以恢复窦性心律。然而，ECV 是否会影响消融后 AF 患者的临床结果并不一致。我们旨在探讨 ECV 对 AF 导管消融后 3 个月内复发患者的 AF 复发和再住院的 1 年影响。
