1. A defibrillating simulator comprises: an apparatus for adapting a defibrillator for training, the apparatus comprising: a pair of electrode covers to be mounted on electrodes of the defibrillator for receiving an electrical discharge generated by the defibrillator delivered through the electrodes; an impedance connected to the pair of electrode covers to receive therethrough the electrical discharge and absorb some of the electrical discharge to generate an electrically reduced electrical discharge; an analyzer for analyzing the electrically reduced electrical discharge and providing analysis data representative of the electrical discharge; a scenario unit for providing at least one training scenario comprising physiological data; and a processing unit receiving the training scenario and the analysis data, the processing unit correlating the analysis data with the training scenario to generate training results.
