The impact of electrocution on the human body is related to the size of the current, the length of the current duration, the path of the current and the size of the voltage and many other factors, which can cause different degrees of damage to the human body: 1. If the current is small when the human body is electrocuted, the patient may have a slight numbness and tingling sensation. If the current is larger, it may cause the heart rate to accelerate, and even the risk of ventricular fibrillation. 2, the longer the contact time between the electrocution current and the body, the greater the damage to the human body, in general, the survival rate of electrocution within 1-5 minutes of active resuscitation 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.
