1. A pacemaker for regulating a patient'"'"'s heart, comprising:

  • a measuring element for measuring an evoked depolarization potential indicative of the diastolic volume of blood in a chamber of the patient'"'"'s heart;

    a pacing parameter generator for generating a pacing parameter; and

    a pacing pulse generator for generating pacing pulses for said heart in accordance with said pacing parameter;

    wherein said pacing parameter generator includes a selector for adjusting said pacing parameter to maximize a cardiac output indicated by said evoked depolarization potential at different pacing rates.
