Abstract

Five cases of WPW syndrome associated with bundle branch block were presented. In 3 cases the block affected the right and in 2 cases the left branch. Although tracings taken before and after pre-excitation were shown in several cases, they were not considered indispensable to the correct diagnosis, because it could be definitely ascertained by inspection of a single vectorcardiogram and electrocardiogram, provided that the premature ventricular depolarization occurred in the chamber with the intact bundle branch. Both methods of registering the electrical activity of the heart were accurate, although in one case, the changes in the vectorcardiogram were clearer than those in the scalar electrocardiogram.
