People who are electrocuted by 220v have different time of death according to different situations. After electric shock, if the electric shock current is relatively small and the contact time is relatively short, the general symptoms will be relatively mild.

If the contact current is relatively large, there will be some serious symptoms, including general fatigue, tachycardia, persistent muscle twitching, coma, muscle paralysis and contraction at the current site, dizziness and so on. Some can die on the spot, and some can be given first aid.

After people get an electric shock, those who get an electric shock should quickly get rid of the power supply. Pull down the power switch or unplug the power plug immediately. If you can't find or disconnect the power supply in time, you can connect the wires with insulators such as dry bamboo poles and wooden sticks. Get the patient out of the electrical environment immediately, and then observe the patient's consciousness and vital signs. If the patient loses heartbeat and breathing, cardiopulmonary resuscitation should be performed immediately.

If there is a wound near the electric burn, the surrounding wound should be disinfected and bandaged in time. Then call 120 immediately. When cardiac arrest occurs, artificial respiration and chest compressions should be taken in time to carry out cardiopulmonary resuscitation.
