1. A cardiac stimulator comprising:

  • a cardiac sensor, wherein the cardiac sensor senses a measure of heart function and wherein the cardiac sensor produces an output signal indicative of the heart function measure;

    a processor, wherein the processor comprises instructions for producing a first alert signal if the heart function measure is indicative of ischemia;

    a waveform generator, wherein the waveform generator produces a stimulation signal in response to the first alert signal and wherein the stimulation signal comprises a leading anodal phase and a trailing phase cathodal phase that is produced after two or more leading anodal phases and wherein the trailing phase follows a preceding leading anodal phase after a delay of from 0 to about 0.25 milliseconds;

    andan electrode for applying the stimulation signal to the cardiac tissue.
