背景资料：选择性心脏复律后房颤（AF）的复发率很高。假设：本研究旨在确定持续性AF患者在没有伴随I类和LII类抗心律失常药物的情况下成功电复律和首次电复律后维持窦性心律的临床预测因素。连续门诊患者（n = 166）持续房颤> 1个月，计划择期心脏复律，前瞻性纳入研究。结果：患者平均年龄68岁（45-83岁），房颤持续时间5个月（1-48个月）。124例（75%）患者建立了窦性心律。在多变量分析中，只有房颤持续时间< 6个月（p < 0.04，比值比[OR] 2.2，95%可信区间[CI] 1.1 - 4.7）和患者体重（p <0.05），
Background: The recurrence rate of atrial fibrillation (AF) after elective cardioversion is high.Hypothesis: The study aimed to identify clinical predictors for successful electrical cardioversion and maintenance of sinus rhythm after a first electrical cardioversion in patients with persistent AF without concomitant antiarrhythmic drugs of class I and LII.Methods: Consecutive outpatients (n = 166) with persistent AF for > 1 month, scheduled for elective cardioversion, were prospectively included in the study. A clinical investigation, echocardiographic assay, and Kelter electrocardiogram (ECG) before and ECG 4 weeks after cardioversion, were performed in all patients.Results: The mean age of the patients was 68 years (range 45-83) and duration of AF was 5 (1-48) months. Sinus rhythm was established in 124 (75%) patients. In multivariate analysis, only duration of AF < 6 months (p < 0.04, odds ratio [OR] 2.2, 95% confidence interval [CI] 1.1 to 4.7) and patients weight (p
