It consists of metal discs about 3-5 cm in diameter and areattached to highly insulated handles. Most of the conventional electrode systems are circular, alittle concave with insulated back-side.Electrode gels are usually employed to reducecontact impedance of the interface. 2) Internal Electrodes : Used for direct cardiac stimulation.
