Predictors of Atrial Mechanical Sensing and Atrioventricular Synchrony with a Leadless Ventricular Pacemaker: Results from the MARVEL 2 Study

The MARVEL 2 study assessed the efficacy of atrio-ventricular synchronous pacing with a Micra leadless pacemaker. Average AV synchrony (AVS) was 89.2%. Previously, low amplitude of the Micra-sensed atrial signal (A4) was observed to be a factor of low AVS.
