摘要(Abstract)：
目的探讨Lasso电极标测下节段性肺静脉电隔离术对心房颤动(房颤)的疗效及其影响因素。方法对120例(其中男性105例;平均年龄50.0±8.6岁)行节段性肺静脉电隔离术的患者(包括阵发性房颤99例,持续性房颤21例),分析其年龄、性别、房颤类型、左心房大小、房颤病史、左心室射血分数、合并高血压与首次术后疗效的关系。结果99例阵发性房颤中首次治愈52例,治愈率52.5%;21例持续性房颤中首次治愈6例,治愈率为28.5%。单因素分析示房颤首次术后复发与左心房扩大、持续性房颤及年龄显著相关;阵发性房颤再次术后治愈率有高于持续性房颤的趋势,但差异无统计学意义(P=0.094)。逻辑回归分析结果只有左心房扩大是首次术后房颤复发的独立危险因素。结论节段性肺静脉电隔离首次术后阵发性房颤治愈率可达50%左右。左心房扩大是房颤复发的独立危险因素,高龄及持续性房颤影响房颤的首次术后治愈率。
