An implantable cardiac device minimizes apnea burden. In one implementation, the device administers a series of cardiac pacing trials using a different value for a pacing parameter in each trial and then measures an apnea burden corresponding to each trial in order to determine a value which reduces apnea burden when used for ongoing cardiac pacing. In one implementation the implantable cardiac device performs series of trials in cycles, during which a first series of trials determines a value for a first pacing parameter for reducing apnea burden while other pacing parameters are held constant. Subsequent series of trials subject the other pacing parameters, in turn, to their own series of pacing trials while holding the non-subjected pacing parameters constant. Through multiple cycles, the device optimizes each parameter in turn based on continually improving values for the other pacing parameters.
