摘　　要：目的探讨持续性心房颤动(简称房颤)电复律术后近期复发的预测因素,并初步探讨其临床意义。方法62例行电复律的持续性房颤患者,分析患者的年龄、性别、病史、左房大小、P波终末电势(PtfV1)、二尖瓣狭窄程度、左室射血分数、左房射血力、VE/VA、合并高血压与电转复术后2个月内复发的关系。结果62例电复律后2个月内复发22例,复发率35.5%,单因素分析示电转复后左房扩大、二尖瓣狭窄、PtfV1异常与房颤近期复发显著相关,多因素逻辑回归分析结果只有左房扩大是电转复术后持续性房颤复发的独立危险因素。结论左房扩大是持续性房颤电复律术后复发的独立危险因素,二尖瓣狭窄及PtfV1异常使持续性房颤电复律术后的近期复发率增高。Objective To evaluate the predictors of recurrence of persistent atrial fibrillation （AF） after electroversion in the near future. Methods Electroversion was performed in 62 consecutive patients with persistent AF. The relationship between the recurrence of AF after electroversion and variables including age, sex, AF history, left atrial diameter, Pwave terminal force of V1（ PtfV1 ） , presence of mitral stenosis, left ventrieular ejection fraction, left atrial ejection force, VE/VA , presence of hypertension were analyzed. Results AF was recurrent in 22 （35.5%） of the 62 patients with persistent AF after electroversion in two months. Univariate analysis showed that left atrial enlargement （ P 〈 0. 001 ） , mitral stenosis （ P =0. 012 ） and PtfV1 abnormality were related to the recurrence of persistent AF. Logistic regression analysis revealed that left atrial enlargement was the only independent risk factor for recurrence of AF. Conclusion Left atrial enlargement is the only independent risk factor for recurrent persistent AF after eleetroversion; mitral stenosis and PtfV1 ab- normality increase the recurrence rate of persistent AF after electroversion in short-term.
