1. An implantable cardiac stimulator to perform pacing of a heart, the heart having an intrinsic atrial firing rate, the cardiac stimulator comprising:

  • plural electrodes adapted to applying pacing stimuli to the heart; and

    pulse generating circuitry connected to the plural electrodes and adapted to generate electrical pulses as biphasic pacing stimuli, wherein the biphasic stimulation comprises an anodal stimulation phase followed by a cathodal stimulation phase;

    wherein a series of pacing stimuli are applied to at least one ventricle having an initial pacing rate, the initial pacing rate being slightly greater than the intrinsic atrial firing rate, and wherein the pacing rate is decreased over time from the initial pacing rate to a minimum pacing rate that is slightly less than the intrinsic atrial firing rate.
