It is possible to survive an electric shock of 230 volts, but it is important to note that it is still dangerous and can cause serious injury. The degree of injury and the chance of survival depend on various factors, such as the duration of contact, the moisture on the skin, the person's health condition, and the level of insulation at the point of contact.

An electric shock of 230 volts can have the following effects:

1. Muscle contraction: The electric current can cause the muscles to contract, which may lead to an involuntary cramping of the body. This can hold the person to the electrical circuit, making it difficult to break free.

2. Burns: Contact with 230 volts can cause burns at the points where the current passes through the body. The severity of the burns depends on the current strength and duration of contact.

3. Arrhythmias: An electric shock of 230 volts can cause arrhythmias, which can lead to cardiac arrest. It is possible to survive these arrhythmias if medical help is provided quickly.

It is crucial to seek immediate medical assistance after a 230-volt electric shock, even if the person seems to have recovered or has no visible injuries. Electric shocks are serious and can cause internal injuries that are not immediately apparent.

It is always advisable to be cautious when handling electricity and to take necessary safety precautions to prevent accidents. Professional electricians should be hired for electrical work, and safety rules and guidelines should be followed at all times.
