Life-saving tip: If you see someone get hit by lightning or is otherwise electrocuted the lethality is due to the heart going into ventricular fibrillation. Therefore, you should check for a pulse and if absent, do a precordial thump, which is a fairly hard and sharp blow to the sternum. Do it once and check for a pulse and if there’s no pulse, do it again and check for a pulse. If there is still no pulse, start chess compressions and get help. If you are uncomfortable with a precordial thump, go directly to chest compressions after checking for a pulse.
