摘　　要：目的探讨"正常化"室性融合波的诊断和发生机制。方法回顾分析1993年1月至2011年10月间在我院住院和门诊心电图有束支阻滞特征伴融合波正常化的12导联心电图和动态心电图65例,分析患者的临床特点。结果 65例患者中完全性右束支阻滞图形39(60%)例,呈完全性左束支阻滞图形23(35.4)例,同时呈现两种束支阻滞图形3例(4.6%),完全性房室阻滞伴双重室性自主心律3(4.6%)例。高度房室阻滞伴室性自主心律12(18.5%)例,窦房阻滞伴室性逸搏3(4.6%)例,室性并行心律45(69.2%)例,房性早搏伴室性逸搏2(3.1%)例。结论束支阻滞时出现室性融合波正常化有多种机制,提示存在与束支阻滞同侧心腔起源的心室异位灶。掌握这些心电现象的机制,有助于进一步分析并准确诊断。Objective We retrospectively analyzed the diagnosis and heart function of patients with ＂normalized＂ ventricular fusion wave. Methods Clinical features were analyzed in 65 patients with Bundle branch block. Results We enrolled 65 patients with RBBB, LBBB and/or RBBB＋LBBB, 60%, 35.4% and 4.6% respectively. In the 65 cases, there were 3 cases with complete AVB with double idioventricular rhythm, 12 cases with second degree AVB and idioventricular rhythm, 3 cases with sino-atrial block and ventricular escape, 45 case with ventricular parasystole, and 2 cases with atrial premature beats and ventricular escape. Conclusion It is of significantly important clinic significance in research and diagnose when identifying the types and pathogenesis of these arrhythmias.
