1. A method for discriminating tachycardia for use in a cardiac medical device capable of sensing cardiac signals and delivering cardiac therapies, the method comprising;

  • sensing cardiac signals and detecting a tachycardia episode in response to the sensed cardiac signals;

    delivering a plurality of dual chamber pacing pulses in response to detecting the tachycardia episode;

    applying a tachycardia discrimination blanking interval subsequent to delivering the plurality of dual chamber pacing pulses;

    sensing at least one intrinsic event subsequent to the blanking interval; and

    classifying the detected tachycardia episode as one of ventricular tachycardia and supraventricular tachycardia in response to the at least one sensed intrinsic event.
