Abstract
A method and system (30, 50) for predicting the immediate success of a defibrillatory shock during cardiac arrest are shown. The sequencing of cardiopulmonary resuscitation is determined by an electronic computer (80) based on the probability of success as determined by a comparison of the amplitude spectrum area or the power spectrum area of an electrocardiogram sample and to empirical data. When the probability of successful resuscitation is 80% or greater, immediate defibrillation is implemented. When the probability of success is 20% or less, advanced cardiopulmonary resuscitation is implemented. When the probability of success remains greater than 20% but less than 80% for a period of four minutes, the patient is also defibrillated.
