Ask a question


Also called cardioversion or external electric shock, defibrillation refers to the medical act which consists of administrating a well-defined quantity of electric current into the heart of a patient in order to stop a cardiac emergency. Carl Wiggers was the first to test this technique on animals in the 1940s before applying it a human in 1947. To perform defibrillation, the first-aid worker or health professional uses a defibrillator that is constituted of an electric unit and a mode of transmission (electrodes or conductive palettes).
