Abstract
Abstract A defibrillator and electrode system that gives the user a visible and/or audible indication of the condition of the electrodes and other parts of the defibrillator system prior to deployment of the electrodes and use of the defibrillator. In a preferred embodiment of the method of this invention, a patient simulation and analyze circuit within the defibrillator periodically tests the condition of the system and provides the user with a visual indication of the system's condition.
