摘要：The relatively uncommon masquerading bu-ndle branch block(MBBB),a concept initially ntroduced in 1958 by UNGER,et al.[1]and co-lleagues,refers to a conduction abnormality that consis-ts of the right bundle branch block(RBBB)pattern in the precordial leads,whereas in the limb leads it resembles a left bundle branch block(LBBB).This electrocardiog-raphic pattern signifies an extensive involvement of the left bundle pathway and left ventricle in comparison to a typical bifascicular block,[2]and has been associated with a poorer prognosis,a higher risk of progression to comp-lete heart block,and increased mortality.[2,3]Diagnosing ischemia in patients with MBBB may pose a diagnostic challenge due to the lack of data concerning this specif-ic population.
