1. A system for aborting the initiation of a dual pathway tachycardia in a heart producing cardiac impulses induced as a result of an inciting cardiac impulse, comprising the steps of:

  • determining at least one time range, each time range being an echo zone, following a cardiac impulse within which an inciting cardiac impulse may occur resulting in a dual pathway tachycardia;

    determining at least one time range, each time range being an aborting zone, following an inciting cardiac impulse within which an aborting cardiac impulse may be induced in the cardiac muscle for aborting the dual pathway tachycardia which otherwise would have occurred as a result of the inciting cardiac impulse;

    sensing cardiac impulses in a heart;

    determining a sensed inciting cardiac impulse as a sensed cardiac impulse sensed at a time within the echo zone; and

    inducing an aborting cardiac impulse at a time within the aborting zone in response to sensing an inciting cardiac impulse.
