is a computerized defibrillator which will analyze the victim's heart rhythm and if ventricular fibrillation or fast ventricular tachycardia is present, will instruct the user to deliver an electric shock. The AED provides on-going voice prompts to the operator.
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.
