Various embodiments of a cardiac pacemaker device and methods are provided. In one embodiment a cardiac pacemaker device includes a pulse generator which emits a plurality of stimulation pulses such that each of the plurality of stimulation pulses is separated by a plurality of inter-beat durations, respectively. The pacemaker device further includes a pacing algorithm configured to implement the pulse generator to generate alternately shorter and longer inter-beat durations independent of hemodynamic loading conditions and such that the average inter-beat duration remains constant.
