摘要

本文报道一例伴有正常和降低的收缩性指数(dP/dt, dP/dt/P)交替的边缘性正常心脏的间歇性和有时交替的非速率依赖性左束支传导阻滞。与其他作者的研究结果相比，左束支传导阻滞导致左心室收缩力降低，可能与左束支传导阻滞的位置不同有关(外周vs高位)。

Changes of left ventricular contractility in alternating left bundle branch block.

A case of intermittent and at times alternating, nonrate-dependent left bundle branch block, with alternation of normal and reduced indexes of contractility (dP/dt, dP/dt/P) in a borderline normal heart is reported. The reduction of left ventricular contractility in the presence of left bundle branch block, as compared to what is found by other authors, is supposedly related to a different location of the block in the left branch (peripheral vs high).
