electrode

 [e-lek´trōd]
either of two terminals of an electrically conducting system or cell; specifically, the uninsulated portion of a lead that is in direct contact with the body.
active electrode therapeutic electrode.
calomel electrode one capable of both collecting and giving up chloride ions in neutral or acidic aqueous media, consisting of mercury in contact with mercurous chloride; used as a reference electrode in pH measurements.
depolarizing electrode an electrode that has a resistance greater than that of the portion of the body enclosed in the circuit.
hydrogen electrode an electrode made by depositing platinum black on platinum and then allowing it to absorb hydrogen gas to saturation; used in determination of hydrogen ion concentration.
indifferent electrode one larger than a therapeutic electrode, dispersing electrical stimulation over a larger area.
point electrode an electrode having on one end a metallic point; used in applying current.
therapeutic electrode one smaller than an indifferent electrode, producing electrical stimulation in a concentrated area; called also active electrode.

e·lec·trode

(ē-lek'trōd),
1. Device to record one of the two extremities of an electric circuit; one of the two poles of an electric battery or of the end of the conductors connected thereto.
2. An electrical terminal specialized for a particular electrochemical reaction.

electrode

Cardiac pacing A part of an electric conductor through which a current enters or leaves; uninsulated conductive part of a pacing lead or a unipolar implantable pulse generator's casing which makes electrical contact with tissue; electrodes are used to record the electric activity of contracting muscles; electromyographic data is collected by surface electrodes, fine wire and needle electrodes. See Ring electrode, SilverBullet electrode, Tip electrode.
