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, each of the electrode covers comprising an insulator and a conductive medium, the insulator extending around the conductive medium to fully electrically insulate the electrodes; an impedance connected to the conductive medium of 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 for receiving the training scenario and the analysis data, the processing unit for correlating the analysis data with the training scenario to generate training results.
