Cardiovertor/defibrillator with electronics (12) that receives a detection signal from a detection device (16) indicating whether a heart of a mammal is fibrillating, processes the detection signal by running a program and generates a control signal for a stimulation device (17) based on the detection signal in order to allow the stimulation device (17) to provoke defibrillation of the heart by a resuscitating stimulation in the area of the pharynx of the mammal. The apparatus has a nose plug.
