Cardiopulmonary exercise testing following conduction system versus biventricular pacing in heart failure: a substudy of the PhysioSync-HF randomized trial
Cardiac resynchronization therapy (CRT) improves clinical outcomes and functional capacity in patients with heart failure with reduced ejection fraction (HFrEF) and left bundle branch block (LBBB). Conduction system pacing (CSP) has emerged as a physiological alternative to conventional biventricular pacing (BiVP...
