摘要 目的了解体表心电图对右心室流出道室性早搏(室早)消融结果的预测价值。方法收集近2年于我院行右心室流出道室早消融成功的患者49例,全部患者室早心电图V1导联QRS波均呈左束支阻滞(LBBB)形态,且无器质性心脏病。随访1～26个月[(6.9±6.8)月],随访期间有7例复发,复发率为14.3%。按结果分为成功组(42例)和对照组(7例),回顾性分析两组患者术前体表心电图12导联R波幅度、R波时限、QRS时限、胸前导联R波移行导联、Ⅰ导联R波单相以及起搏时12导联心电图与自然发作室早心电图图形相同的导联数等,比较两组患者心电图的特点。结果当胸前导联R波的移行于V1、V2导联(P=0.048);V2导联QRS波群时限(P=0.033)、Ⅱ导联的QRS波群时限(P=0.018)、Ⅱ导联的R波振幅(P=0.024)明显较大时,更易复发,且有统计学意义。结论术前分析心电图有助于临床医生选择合适室早患者作为消融对象,以降低失败风险,提高成功率。
