长期的真性左束支阻滞可引起左室扩大、心功能进行性下降，进而发展为伴有心功能不全的心肌病。这种左束支阻滞性心肌病的发病机制尚不明确，可能与左束支阻滞所致的电-机械活动失同步有关。该病的临床诊断过程与获得性心肌病一致，关键是识别真性左束支阻滞。心脏再同步化治疗能有效逆转左束支阻滞性心肌病。

Long-term true left bundle branch block can cause left ventricular dilatation,progres-sive decrease of cardiac function,and further develop into cardiomyopathy complicated by cardiac functional insufficiency.Its pathogenesis is not clear,which is possibly related to the synchroniza-tion loss of electrical and mechanical activities caused by left bundle branch block.The diagnostic method of the disease is consistent with that of other acquired cardiomyopathy,the highlight of which is to identify true left bundle branch block.By cardiac resynchronization therapy,left bundle branch block-induced cardiomyopathy can be reversed effectively.
