Bilateral bundle branch block

American Heart Journal, 1955
Abstract 1. 1.

Bilateral Bundle Branch Block

Cardiac Electrophysiology Clinics, 2021
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
