1. Cardiac ectopic heat detection apparatus which comprises:

  • means for sensing cardiac depolarization including first means for sensing depolarization of a first area of cardiac tissue and second means for sensing depolarization of at least one other area of cardiac tissue, said first area being an area of earlier activation within the ventricular conduction system than any of said other areas;

    output means; and

    means interconnecting said output means and sensing means for providing a signal to said output means only following the occurrence of cardiac depolarization sensed by said second means and not preceded by a depolarization sensed by said first means.
