Automated Defibrillator

Automated defibrillator is a lightweight and portable medical device that delivers electroshock (defibrillation) to the heart through the chest via pads. This shock stops the irregular cardiac contractions for a very short period of time, allowing the heart to return to its normal contractions. Sudden cardiac arrest leads to cardiac dysfunction. Unless the shock is delivered in a very short time period, this could lead to death. 

The most common form of sudden cardiac arrest is ventricular fibrillation, which is rapid and asynchronous cardiac rhythm. When ventricular fibrillation occurs, the heart should immediately be defibrillated, as the patient’s chance of survival decreases by 10% every minute.
