Expanding Benefits from Cardiac Resynchronization Therapy to Exercise-Induced Left Bundle Branch Block in the Setting of Advanced Heart Failure: A Case Report

Exercise-induced left bundle branch block (LBBB) is rarely observed in exercise testing, and usually implies a worse prognosis. Cardiac resynchronization therapy (CRT) is well validated in patients with heart failure with reduced ejection fraction (HFrEF) and LBBB. Although the indications of CRT do not include exercise-induced LBBB, the functional impairment secondary to dynamic electromechanical dyssynchrony could potentially be improved with CRT.
