In brief: Defibrillator
An external defibrillator can be automatic or manned either way either a computer or the operator can determine the patient is having a lethal arrhythmia and electrical energy is delivered to the chest wall and the rhythm can be terminated.

In brief: An ICD?
If you are referring to an implanted cardioverter defibrillator it works as follows: it detects fast heart beats above a threshold set by the cardiologist and programmed into the defibrillator and delivers a shock or atp - pacemaker override, depending on the heart rate.
It will deliver subsequent shocks depending on the heart rate it detects.
