Bundle-branch block

(Science: cardiology, physiology) abnormal conduction through one of the conductive branches which normally supply the right and left ventricles.

Usually results in delayed conduction though either the right or left bundle branches where one ventricle is excited before the other because of absence of conduction in one of the branches of the bundle of his.

Intraventricular block due to interruption of conduction in one of the two main branches of the bundle of his and manifested in the electrocardiogram by marked prolongation of the qrs complex; block of each branch has distinctive qrs morphology.
