INTRODUCTION  THE CONCEPT of bundle branch block was introduced by Eppinger and Rothberger 1 in 1909 in Vienna, when, during the course of electrocardiographic studies of the effects of trauma to the myocardium induced by the injection of silver nitrate solution, they suspected that the appearance of broadened ventricular complexes meant damage to a main bundle branch. During the next few years, they
