Depends: Lbbb is abnormal. It may be associated with coronary heart disease, high blood pressure, an enlarged heart, or cardiomyopathy (heart muscle disease). Rarely, it can be congenital (present at birth). The significance of LBBB depends on the presence or absence of associated heart disease and whether it is a new finding or has been present for several years. May need echocardiogram and/or heart cath.
