At low currents, AC electricity can disrupt the nerve signals from the natural pacemaker in your heart and cause fibrillation. This is a rapid fluttering vibration, too weak to pump blood. If the rhythm isn't restarted with a defibrillator, it's usually fatal.

How does a person die from electrocution?

The mechanism of death in electrocutions is most commonly a cardiac dysrhythmia, usually ventricular fibrillation, less commonly paralysis of the respiratory muscles, and rarely a direct effect on the brainstem as a result of passage of the current through the head and neck.

When you get electrocuted do you die?

Electric shocks can cause injuries that are not always visible. Depending on how high the voltage was, the injury may be fatal. However, if a person survives the initial electrocution, a person should seek medical attention to ensure that no injuries have occurred.
