ABSTRACT:
The invention is directed to techniques for attempting to restore a patient to a normal sinus rhythm. In a patient experiencing asystole or pulseless electrical activity, defibrillation therapy may be ineffective. The invention is directed to techniques for delivering one or more shocks to induce ventricular fibrillation in the patient, followed by one or more defibrillation shocks to restore normal sinus rhythm. A defibrillator may deliver the fibrillation and defibrillation therapies. The invention may also include techniques for estimating the probability that the patient will respond favorably to the defibrillation therapy, and delivering defibrillation therapy when the therapy has a good probability of success.
