Abstract

The characteristics of the speed of inscription of QRS loops in left bundle branch block were investigated by the spatial velocity electrocardiography. The characteristic findings of QRS waves of the spatial velocity electrocardiogram were that the velocity decreased markedly at the initial third of QRS interval, and then increased again holding certain higher level than those of right bundle branch block. Analysis of QRS waves of the spatial velocity electrocardiogram suggested that the conduction delay might be present not only in the ventricular septum but also in the free left ventricular wall in this condition.
