A defibrillator is a medical device that delivers a high-energy electric shock to the heart to restore a normal heart rhythm. It is used to treat sudden cardiac arrest, a condition in which the heart suddenly stops beating.
Defibrillators are typically found in public places such as airports, shopping malls, and sports arenas. They are also used by emergency medical responders and in hospitals. Defibrillators are easy to use and can save lives.
