An atrial cardioverter for cardioverting atria of a heart while sustaining atrial pacing of the heart. The cardioverter includes a pacer for pacing the heart in one of a plurality of modes including an atrial pacing, atrial inhibited mode, and an atrial pacing, ventricular inhibited mode, an atrial tachyarrhythmia detector for detecting an atrial tachyarrhythmia of the heart, and a mode control for changing the mode of the pacer from the atrial pacing, atrial inhibited mode to the atrial pacing, ventricular inhibited mode responsive to the atrial tachyarrhythmia detector detecting an atrial tachyarrhythmia of the heart. A cardioverter stage applies cardioverting energy to the atria responsive to the atrial tachyarrhythmia detector detecting an atrial tachyarrhythmia and after the pacer mode change. |
