摘要(Abstract)：
目的观察阵发性心房颤动(房颤)环肺静脉电隔离术(CPVI)中不同观察时间内肺静脉传导急性恢复的发生率,并评价再次电隔离术对于临床疗效的影响。方法入选阵发性房颤患者90例,其中男性51例,女性39例,平均年龄56·4±12·3(45～73)岁;随机分为三组行CPVI,组A实现肺静脉电隔离不予观察,组B电隔离后观察时间30min,组C电隔离后观察时间60min,评价肺静脉传导恢复发生率并对其再次行电隔离术。术后随访心电图和24小时动态心电图评价疗效。结果所有患者顺利完成消融术。组A平均手术时间显著短于组B和组C。肺静脉隔离时间和X线透视时间三组中每两组差异均无统计学意义。组B左肺静脉隔离后30min传导恢复8例(25%),60min电位恢复共10例(31·2%);右肺静脉隔离后30min传导恢复6例(18·8%)。组C左肺静脉隔离后30min传导恢复9例(30%),60min传导恢复共11例(36·7%);右肺静脉隔离后30min7例(23·3%)传导恢复,60min共8例(26·7%)传导恢复。平均随访6·7±2·3(4～9)个月,组A17例(60·7%)、组B27例(84·3%)、组C26例(86·7%)无房性快速性心律失常发作,P=0·04。结论环肺静脉电隔离术中肺静脉传导急性恢复率为30%左右,多数发生在肺静脉隔离后30min内,再次电隔离术有助于提高消融成功率。
