1. A cardiac pacemaker for providing optimal pacing therapy to a patient, the pacemaker having a plurality of pacing modes, the pacemaker comprising:

  • first sensing means for providing a signal indicative of cardiac performance;

    pulse generating means for generating stimulation pulses to a patient'"'"'s heart;

    exercise detecting means for detecting the exercise state of a patient;

    means for determining when the cardiac performance is maximized based on the first sensing means;

    processing means for controlling the pulse generating means to operate in the plurality of pacing modes and for determining an optimal pacing mode when the determining means indicates that the cardiac performance is maximized for a current exercise state of the patient; and

    means for automatically switching from a current pacing mode to the optimal pacing mode.
