DOIAbstract
Cardiac resynchronization therapy (CRT) reduces morbidity and mortality in heart failure with reduced ejection fraction (HFrEF). CRT efficacy is greater in left bundle branch block (LBBB). This study aimed to determine if strict LBBB criteria predicts an improved QRS duration and left ventricular ejection fraction (LVEF) response after CRT
