What Is an Automated External Defibrillator?
... An automated external defibrillator (AED) is a lightweight, portable device that delivers an electric shock through the chest to the heart. The shock can stop an irregular heart rhythm and allow a normal rhythm to resume following sudden cardiac arrest. Sudden cardiac arrest is an abrupt loss of hea ...
