AED - Automatic External Defibrillator - A defibrillator is a device developed to combat cardiac arrest or heart attack brought on by a fibrillation or irregular heart rhythm. This irregularity causes the heart to stop receiving enough blood and can result in sudden death if not treated properly.
The defibrillator delivers small electronic shocks to the heart designed to stimulate a return to a more manageable rate and rhythm. Specifically, an electric current is channel through the body into the heart via electrodes or paddles placed on the chest. The current causes the heart muscle to spasm or jolt, and hopefully ends any fibrillation threatening blow flow.
