Defibrillator

An automated external defibrillator (AED) is a device widely available in public which acts to defibrillate (cardiovert) a patient out of serious heart rhythm disorders, frequently ventricular tachycardia or ventricular fibrillation.

An automated implantable cardioverter defibrillator (ICD or AICD) is a permanent device in which a lead (wire) inserts into the right ventricle and monitors the heart rhythm.
