An implantable medical interventional device is disclosed for treating any of multiple cardiac dysrhythmias that may be suffered by a patient in whom the device is to be implanted, by automatic selection of an appropriate therapeutic regimen from among a plurality of such regimens the device is capable of delivering according to the particular dysrhythmia being experienced by the patient at the time, through enhanced recognition and discrimination of the dysrhythmia and its probable origin. Upon recognition and discrimination of the dysrhythmia, the device applies the selected regimen to the patient's heart to treat the dysrhythmia at its source. The device includes a DDD pacer operatively combined with an atrio-ventricular cardioverter/defibrillator, and a cardiac dysrhythmia evaluator incorporating logic responsive to cardiac signals sensed by the combined DDD pacer/cardioverter/defibrillator when the device is implanted in the patient for developing generalized findings to determine the identity and origin of a sensed dysrhythmia and to respond accordingly by selecting an appropriate therapeutic regimen to be delivered to the patient's heart.
