Optimizing atrioventricular synchrony in young adults implanted with leadless pacemakers

Abstract

The MicraTM AV is a second generation single chamber leadless pacemaker which enables atrioventricular (AV) synchronization through use of its 3-axis accelerometer (previously only used for rate modulation). Although AV-synchronous pacing provides several advantages compared with ventricular-only pacing, achieving adequate AV synchrony with this system can be challenging, particularly in young active patients.
