1. An implantable cardiac device, comprising:

  • a sensing channel for sensing cardiac activity;

    a pacing channel for delivering pacing pulses;

    circuitry for recording an electrogram from the sensing channel of an evoked response to a pace and for detecting a change in the recorded electrogram indicative of cardiac ischemia by comparing the recorded electrogram with a reference electrogram;

    a drug delivery apparatus for delivering a quantity of a cardiac drug; and

    , circuitry for actuating the drug delivery apparatus upon detection of cardiac ischemia.
