In this mode, the pacemaker paces and senses in the atrium, the ventricle, or both. On sensing activity in either chamber, the pacemaker inhibits pacing in that chamber. Or, on sensing atrial activity, the pacemaker may trigger ventricular pacing.

The description matches the DDD mode of pacemaker operation, where the device can pace and sense in both the atrium and ventricle. It inhibits pacing upon sensing natural activity and can trigger ventricular pacing following atrial sensing, aligning with the DDD functionality.

In This Mode, the Pacemaker Paces and Senses in the Atrium
