An atrial cardioverter (30) includes a pacemaker (55) for applying atrial pacing pulses to an atrium (16) of a heart (10), an atrial tachyarrhythmia detector (60) for detecting an atrial tachyarrhythmia of the heart, and an R wave detector (52) for detecting R waves of the heart. A cardioverting stage including a timer (68) for timing time spans between immediately successive R waves, and atrial pacing pulses applies cardioverting electrical energy to t he atria of the heart responsive to a time span exceeding a predetermined duration.
