    Abstract: This invention relates to disposable electrode pads which may be used with cardiac devices, such as ECG, defibrillator or pacemaker devices. The pads are in the form of a foil bag containing an electrolyte. The bags are easily rupturable so that the electrolyte is applied to the surface of the human body.
