Claim One:
1. A device comprising: a monitoring module to monitor electrical activity of a heart of a patient; an electrical source capable of generating a first electrical shock and a second electrical shock; at least two electrodes to deliver the first and second shocks to the heart; and a processor configured to determine that the heart is in asystole and, in response to the determination of asystole, control the electrical source to generate the first electrical shock in a manner intended to induce fibrillation, wherein the processor is further configured to control the electrical source to generate the second electrical shock in a manner intended to defibrillate the heart subsequent to the generation of the first electrical shock, and wherein the processor is further configured to compute, following delivery of the first electrical shock, a value representing an estimated effectiveness of the second electrical shock in defibrillating the heart prior to delivery of the second electrical shock, and wherein the processor is further configured to control delivery of the second electrical shock when a comparison between the value representing the estimated effectiveness of the second electrical shock and a predetermined value indicates that delivery of the second shock has an acceptable probability of defibrillating the heart.
