May inform ECG-pathology links in masquerading BBB; leaves open validation in larger cohorts before clinical adoption.
Masquerading bundle-branch block is anatomically associated with severe bilateral bundle branch lesions, massive ventricular hypertrophy, and septal myocardial damage.
Unger et al. (1958) studied this question. In two patients with electrocardiographically identified masquerading bundle-branch block, detailed pathological evaluation revealed specific conduction system abnormalities.
