"Durban cardiologist Dr Donovan Parker said a stun-gun could kill a person with a weak heart "in a matter of seconds". "The stun-gun is designed to key into the nervous system. It dumps its energy into the muscles at a high pulse frequency that makes the muscles work very rapidly, but not very efficiently. This rapid work cycle depletes blood sugar by converting it into lactic acid, all in just seconds. This results in energy loss and makes it difficult for the person to move and function."
