1. A medical device for treating cardiac dysfunction, comprising:

  • implantable sensor means for obtaining one or more cardiac parameters of a patient;

    a processor means for processing the one or more cardiac parameters to determine whether cardiac dysfunction is present;

    therapy delivery means for delivering therapies upon a determination of cardiac dysfunction being present, the delivered therapies comprising both stimulation of excitable tissue to treat the cardiac dysfunction and modulation of the excitable tissue'"'"'s effective refractory periods to achieve a desired effective refractory period; and

    wherein the stimulation to treat the cardiac dysfunction comprises post extrasystolic potentiation, and wherein the refractory period modulation comprises refractory period stimulation shortening of one or more of an initial refractory period and a secondary refractory period.
