  • Publication number: 20100094368
    Abstract: A method and/or system for inducing ventricular fibrillation (VF) of the heart for treatment of post-countershock pulseless electrical activity (PEA) or asystole. In certain example embodiments, it has been found that reinduction of ventricular fibrillation, followed by restoration of blood flow with cardiopulmonary resuscitation (CPR), can make subsequent countershocks more successful in restoring a heart rhythm associated with blood flow.
