完全性左束支传导阻滞的心向量图诊断已屡见报道。近年来,关于完全性左束支传导阻滞的病因、预后均有不同的看法。特别是完全性左束支传导阻滞电轴偏移的问题更有所争论。完全性右束支传导阻滞伴有显著的电轴左偏或右偏,分别代表右束支传导阻滞合并左束支前分支及后分支阻滞。而完全性左束支传导阻滞时电轴偏移的意义
Complete left bundle branch block heart vector diagram diagnosis has been frequently reported. In recent years, there are different opinions on the etiology and prognosis of complete left bundle branch block. In particular, the issue of complete axial displacement of the left bundle branch block is more controversial. Complete right bundle branch block accompanied by significant axial left deviation or right deviation, respectively, on behalf of the right bundle branch block combined with left bundle branch and branch after the left branch block. The significance of electrical axis offset in complete left bundle branch block
