The body is affected by electrocution, generally speaking, based on the size of the current, the length of time the current lasts, the path of the current and the size of the voltage to assess the degree of damage to the body. 1, if the body is electrocuted when the current is small, the patient may have a slight numbness, tingling sensation. If the current is large, it may cause an increased heart rate and even the risk of ventricular fibrillation. 2, the longer the contact time between the electric current and the body, the greater the damage to the human body, in general, the survival rate of active resuscitation within 1-5 minutes of electrocution is about 90%, more than 10 minutes only 60% of the survival rate. 3, the path of the current through the body is different, the damage to the human body also differs, such as the current through the head 4, the higher the voltage when electrocuted, the greater the danger to the human body, high-voltage electricity can cause instant death of the body.
