Po-621-03 dual-chamber leadless pacemaker enables robust atrioventricular synchrony in various postures and pacing configurations

Dual-chamber leadless (DDD) indicated patients require atrioventricular (AV) synchronous pacing involving beat-by-beat, wireless communication between devices. Implant-to-implant (i2i™) communication enables true AV synchrony. At each paced or sensed event, one leadless pacemaker (LP) communicates wirelessly with the other. Changes in posture could affect orientation of the LPs and thereby potentially impact i2i communication.
