Septal to lateral delay: a practical ECG-derived measure to determine left ventricular dyssynchrony in left bundle branch pacing
Left bundle branch pacing (LBBP) is becoming established as an integral part of modern cardiac resynchronization therapy (CRT). In heart failure patients undergoing LBBP, it remains uncertain how to determine adequacy of electrical resynchronization and whether an additional coronary sinus lead is warranted. Alth...
