An automated external defibrillator or automatic electronic defibrillator (AED) is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation (VF) and pulseless ventricular tachycardia, [1] and is able to treat them through defibrillation, the application of electricity which stops the arrhythmia, allowing the heart to re ...
In 1972 Bernard Lown, the inventor of the external defibrillator, and Paul Axelrod stated in the journal Circulation – "The very rare patient who has frequent bouts of ventricular fibrillation is best treated in a coronary care unit and is better served by an effective anti-arrhythmic program or surgical correction of inadequate coronary ...
A wearable cardioverter defibrillator is a portable external defibrillator that can be worn by at-risk patients. [21] The unit monitors the patient 24 hours a day and can automatically deliver a biphasic shock if VF or VT is detected. This device is mainly indicated in patients who are not immediate candidates for ICDs. [22]

A defibrillator is a machine that produces a defibrillation: electric shocks that can restore the normal heart function of the victim. The common model of defibrillator out of an hospital is the automated external defibrillator (AED), a portable device that is especially easy to use because it produces recorded voice instructions.
Automated external defibrillators (AED) are portable electronic devices designed to analyze the heart rhythm and inform the operator whether defibrillation is required. They are intended for people of the general population with an unknown risk for heart failure and are usually available in public places and first responder ambulances.
An automated external defibrillator (AED) is a portable electronic device that diagnoses and treats cardiac arrest by re-establishing an effective heart rhythm. This treatment is called defibrillation, which applies an electric shock to the entire heart muscle, uniformly clearing the electrical activity of the heart, hopefully allowing it to resynchronize.
Once an automated external defibrillator (AED) has been acquired the rescuer should then finish the round of CPR, use the AED and then begin another round of CPR. However the AED will usually notify the rescuer of any impediments to continued CPR (such as a sinus rhythm or asystole) in which case the rescuer may be prompted to cease CPR.
