Left bundle branch block (LBBB) and right bundle branch block (RBBB) are classic manifestations of bundle branch conduction disorders. However, a third form that is uncommon and underrecognized may exist that has features and pathophysiology of both: bilateral bundle branch block (BBBB). This unusual form of bundle branch block exhibits an RBBB pattern

Abstract 1. 1. An electrocardiographic diagnosis of bilateral bundle branch block can be made in rare instances in which conduction in the branches is not completely interrupted and the degree of block in one of the branches is less than in the other on some occasions and greater on others; this allows the patterns of right and left bundle branch

Alternating bundle branch block
Journal of Electrocardiology, 1980Mechanisms postulated for alternating bundle branch block are incomplete- and cycle-length-dependent-block in both the right and left bundle branches. A patient with severe longstanding cardiac conduction disease who developed alternating bundle branch block during treatment for advanced ischemic heart disease and malignant ventricular arrhythmia is ...

Abstract A description is given of a mother who died at the age of 35 years, and of 4 young siblings, all of whom revealed right bundle branch block as an isolated finding.

THE LOCALIZATION of block in the main branches of the bundle of His was clarified by the studies of Wilson and his co-workers.1In this regard precordial electrocardiography proved to be of great value. The clinical significance of these findings, however, has been confusing, and it is well known that right or left bundle branch block is commonly ...

Left bundle branch block masquerading as right bundle branch block
American Heart Journal, 1954Abstract 1. 1. Four cases having electrocardiograms with the following features have been presented: (a) signs of left bundle branch block in the limb leads; (b) signs of right bundle branch block in the precordial leads; (c) qR deflections in aVR. 2. 2.

Left bundle-branch block is ventricular excitation that is prolonged 0.12 second or more. It creates a specific pattern on vectorcardiogram and electrocardiogram, but changes in standardization are often needed to bring out detail.
