An atrial defibrillator applies cardioverting electrical energy to the atria of a heart when in need of cardioversion. The atrial defibrillator includes an atrial fibrillation detector for determining if the atria of a heart are in need of cardioversion, and a therapy sequencer for performing a therapy sequence to apply cardioverting electrical energy to the atria when the atria are in need of cardioversion. The therapy sequence is terminated when the atrial fibrillation detector fails at least twice in succession to determine that the atria are in need of cardioversion. As a result, a greater atrial fibrillation detection sensitivity is employed for terminating a therapy sequence as is employed for initiating the therapy sequence.
