The procedure involves the delivery of an electric shock to the heart which causes depolarisation of the heart muscles and re-establishes normal conduction of the heartâs electrical impulse. The machine used to deliver this therapeutic shock to the heart is called a defibrillator.The different types of defibrillators used include external defibrillators, transvenous defibrillators and implanted defibrillators.Defibrillation was first presented by Prevost and Batelli, two physiologists from University of Geneva, Switzerland in 1899.he procedure involves the delivery of an electric shock to the heart which causes depolarisation of the heart muscles and re-establishes normal conduction of the heartâs electrical impulse.
