The role of atrioventricular delay in left bundle branch stimulation: when diastole is more important than systole
We present a clinical case of an 86yearold patient with initially preserved left ventricular ejection fraction, left bundle branch block, and sick sinus syndrome, who underwent implantation of a dualchamber pacemaker with selective left bundle branch pacing. With a programmed short atrioventricular delay (100/120 ms) a...
