The electrocuted person should check the whole body condition, especially breathing and heartbeat, immediately after getting off the power supply. Then consult a doctor in time for ECG, urine test and blood test. 1. Systemic condition: check the patient’s respiration and heartbeat immediately after disconnecting from the power source, if not, chest compressions and other rescue measures should be given immediately, otherwise the patient’s life will be jeopardized. 2. Electrocardiogram: After the patient has experienced electric shock, the current acting on the heart will easily cause ventricular fibrillation, which may lead to arrhythmia. Therefore, patients should undergo ECG to see if there is any myocardial damage or atrioventricular block. 3 Urine routine examination: If the patient experiences electric shock, the current will be transmitted directly to the kidneys, then the organ failure will occur. Patients can be tested for kidney damage through routine urine tests, which can look for normal hemoglobinuria and myoglobinuria values. 4. Blood test: If the patient has experienced electric shock, it may cause skin burns. Therefore, routine blood tests can be performed at the hospital to see if white blood cells, platelets or neutrophils are at normal levels. It is important to note that if a patient experiences an electric shock injury, it is important to turn off the power as soon as possible or strip the power supply with a non-conductive object to avoid a life-threatening situation.
