Tailoring the Atrioventricular Interval During Left Bundle Branch Pacing: Playing With Fusion.
BACKGROUND Optimization of biventricular pacing for cardiac resynchronization therapy (CRT) with fusion (fusion-optimized intervals method) has been shown to improve left ventricular remodeling. However, information on programming the atrioventricular (AV) interval during left bundle branch pacing (LBBP) is scarce. O...
