Is LBBB a serious heart condition?

Left bundle branch block is a disorder of the heart’s electrical conduction system. Anyone diagnosed with left bundle branch block should have a cardiac evaluation to look for underlying heart disease that requires treatment.

Why is LBBB bad?

LBBB causes some damage on the mechanical function of the LV secondary to asynchronous myocardial activation, which sequentially, may trigger ventricular remodelation and bad prognosis.
