In two patients with electrocardiographically identified masquerading bundle-branch block, detailed pathological evaluation revealed specific conduction system abnormalities.
Masquerading bundle-branch block is anatomically associated with severe bilateral bundle branch lesions, massive ventricular hypertrophy, and septal myocardial damage.

This is a clinicopathologic study of 2 patients who electrocardiographically presented so called "masquerading" bundle-branch block. The conduction systems and the entire hearts of these patients were studied pathologically by methods especially devised by Lev for electrocardiographic correlation. This report is part of a long-term project attempting to ascertain the anatomic substrate of electrocardiographic abnormalities.
