The defibrillator does not restart a stopped heart. On the contrary, its use allows you to stop the work of the heart muscle (myocardium) during a heart attack, so that the body gets a chance to restore a normal sinus rhythm. The use of a defibrillator with the complete cessation of the bioelectric activity of the heart, which corresponds to the isolation on the ECG, does not make sense — this can only be seen in the movies.
