Do defibrillators leave scars

Defibrillators themselves do not leave scars, as they deliver an electric shock through the chest wall without causing physical cuts or abrasions. However, if an external defibrillator is used in conjunction with CPR, there may be bruising or skin irritation at the electrode pads' contact points. For implanted defibrillators, a scar may result from the surgical procedure to place the device under the skin.
