The term you are looking for with the “death punch” is Commotio Cordis.
Also, to be more technically accurate, defibrillators are intended to restart a stopped heart, but only some kinds of stops. What people traditionally think of is Asystole (“flatline”), which is complete lack of electrical activity in the heart. Shock won’t do diddly here, they ded.
Ventricular tachycardia and ventricular fibrillation however have essentially stopped the muscular/mechanical pumping of the heart, because of disjointed electrical activity. This activity is what the defibrillator is intended to reset.
There’s a 4th type called Pulseless Electrical Activity (PEA) where the electrical function is relatively normal, but something external is preventing pumping. Defib won’t help here either, since the electrical portion is working fine.
