Wikipedia

A defibrillator is a medical device that is used to defibrillate the heart. It does this by shocking the heart with an electric current to stop ventricular fibrillation or pulseless ventricular tachycardia. The current is sent through two electrodes. These electrodes are normally either paddles or sticky pads. Each electrode is placed on one side of the heart.

Ventricular fibrillation is a situation of electrical chaos in the heart's conduction system. It changes the normal contractions of cardiac muscular tissue. This causes the heart to stop pumping blood around the body properly. It causes circulatory arrest and death within minutes from hypoxic brain damage. The electric current from a defibrillator stops all electrical activity in the heart by depolarising its electrical system. This lets the hearts normal impulses regain control of the muscular tissue of the heart.

Internal defibrillators.

Implantable cardioverter-defibrillators (ICD) are defibrillators that are designed to defibrillate patients from inside their body. They are put inside people that are at high-risk of going into cardiac arrest and monitor a person's heart rate, rhythm, and waveform, and by comparing atrial and ventricular activity, an implantable cardioverter-defibrillator can detect cardiac arrhythmias and treat them quickly.

External defibrillators.

External defibrillators are often used in hospitals and ambulances, but they are now being used outside of medical environments more as automated extern
