摘　　要：目的 探讨心脏瓣膜病手术同期实施心房颤动（房颤）外科射频消融的患者术后出现房颤复发或心房扑动时,行电复律治疗的效果影响因素.方法 回顾性分析2011年2月至2014年5月在南京鼓楼医院心胸外科行房颤术后电复律治疗的69例患者,多元回归分析筛选影响电复律治疗效果的临床因素.结果 电复律失败14例,电复律成功55例.多元回归分析发现,年龄是电复律失败的独立危险因素,而性别、电复律前左心房内径、电复律前心率是边缘显著的独立危险因素.结论 性别、年龄、电复律前左心房内径、电复律前心率可能影响电复律转复结果,对成功实施电复律治疗有指导价值.Objective The purpose of this study was to explore predictive factors of electrical cardioversion for recurrence of atrial fibrillation （AF） after surgical radiofrequency ablation.Methods Retrospective analysis was made in 69 valvular heart disease patients receiving electrical cardioversion for AF recurrence after concomitant radiofrequency modified Maze operation from February 2011 to May 2014 in Nanjing Drum Tower Hospital.Multivariate regression analysis was used to screen predictive factors for predicting failure of electrical cardioversion.Results Electrical cardioversion was successful in 55 cases,and failed in 14 cases.Multivariate regression analysis indicated that age was the significant risk factor and gender,larger left atrial size and heart rate were edge-significant risk factors for predicting failure of electrical cardioversion.Conclusion Female,elder age,left atrial enlargement and higher heart rate indicated a poor cardioversion possibility by electrical cardioversion for recurrence of AF after surgical radiofrequency ablation.
