Defibrillation is indicated if a shockable rhythm is present.
The two shockable rhythms are ventricular fibrillation and pulseless ventricular tachycardia.
In children 2 to 4 J/Kg is recommended.

In addition, there is increasing use of public access defibrillation.
This involves placing an automated external defibrillator in public places, and training staff in these areas how to use them.
This allows defibrillation to take place prior to the arrival of emergency services and has been shown to lead to increased chances of survival.
Some defibrillators even provide feedback on the quality of CPR compressions, encouraging the lay rescuer to press the person's chest hard enough to circulate blood.
In addition, it has been shown that those who have arrests in remote locations have worse outcomes following cardiac arrest.
