BACKGROUND: Leadless pacemakers (LP) capable of VDD pacing allow for atrioventricular synchrony through mechanical sensing of atrial contraction. Unfortunately, mechanical sensing is less reliable and less predictable than electrical sensing. OBJECTIVE: We evaluated the P wave amplitude during sinus rhythm from pre-operative 12-lead ECGs as a predictor for atrial mechanical sensing in patients undergoing VDD LP implantation. METHODS: Consecutive patients undergoing VDD LP implantation were included in this two-center prospective cohort study...
