在束支传导阻滞时,如出现 H-V 间期延长,表示另一侧束支也有病变,是双侧束支传导阻滞的依据。有些作者认为在常规心电图中,如束支传导阻滞并有第一度心脏传导阻滞,表示有双侧束支传导阻滞。而另一些作者用希氏束电图证明大多数这些病人的传导 In the bundle branch block, such as the extension of H-V interval, said the other bundle branch also has lesions, is the basis for bilateral bundle branch block. Some authors believe that in conventional ECGs, such as bundle branch block with a first heart block, there is a bilateral bundle branch block. Others use His bundle to prove the conduction of most of these patients
