Eppinger和Rothberger在1909和1910年首先报告了传导系统的重要性,可是将左束支传导阻滞(LBBB)误认为右束支传导阻滞(RBBB),这一错误认识几乎持续了25年之久。左束支由His氏束延伸而来,其直径约1～4mm。早年强调分叉起始部为网状。近年来认识到分叉前狭窄的左束支长达1cm。由此分出较狭的前分支,较早分出的较宽的后分支,以及常常由前、后分支之一分出的间隔段三支间存在许多连接。前、后分支分别进入前、后乳头肌内基底部,通过广泛的浦肯
Eppinger and Rothberger first reported the importance of conduction systems in 1909 and 1910, but misinterpreted left bundle branch block (LBBB) as right bundle branch block (RBBB), a misconception that lasted almost 25 years Long. Left bundle branch by His beam extends from the diameter of about 1 ~ 4mm. Earlier emphasis on the beginning of the bifurcation mesh. In recent years, I realized that the left bundle branch anterior to the stenosis up to 1cm. Thus there are many connections between the narrower anterior branch, the wider anterior posterior branch, and the intervening divisions often divided by one of the anterior and posterior branches. The anterior and posterior branches enter the anterior and posterior papillary muscle base, respectively, through a wide range of Purkinje
