B-PO01-024 MECHANICAL AV SYNCHRONY PROVIDED BY A LEADLESS PACEMAKER SUCCESSFULLY TIMES VENTRICULAR ACTIVATION TO THE COMPLETION OF ATRIAL CONTRACTION

Current leadless ventricular pacemakers have the ability to provide AV synchronous (AVS) pacing by tracking late phase right ventricular filling from atrial mechanical contraction. How this accelerometer-based approach translates into appropriate left ventricular filling times is incompletely understood. To characterize left ventricular filling with accelerometer-based AVS pacing among patients with 3rd degree AVB in the MARVEL 2 study....
