An atrial cardioverter and a method of its operation. The cardioverter measures an interval between successive R-waves, defines a ventricular escape interval as a function of the measured interval between successive R-waves and delivers a ventricular pacing pulse at the expiration of the ventricular escape interval in the absence of R-waves during the ventricular escape interval. The cardioverter defines a synchronization interval following delivery of the ventricular pacing pulse, and delivers an atrial cardioversion pulse synchronized to an R-wave occurring after expiration of the synchronization interval, absent R-waves during the synchronization interval.
