electrode /elec·trode/ (e-lek´trōd) a conductor or medium by which an electric current is conducted to or from any medium, such as a cell, body, solution, or apparatus. active electrode in electromyography, an exploring e. 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. esophageal electrode , esophageal pill electrode a pill electrode that lodges in the esophagus at the level of the atrium to obtain electrograms and deliver pacing stimuli. exploring electrode in electrodiagnosis, that placed nearest to the site of bioelectric activity being recorded, determining the potential in that localized area. ground electrode one that is connected to a ground. indifferent electrode reference e. needle electrode a thin, cylindrical electrode with an outer shaft beveled to a sharp point, enclosing a wire or series of wires. patch electrode a tiny electrode with a blunt tip that is used in studies of membrane potentials. pill electrode an electrode usually encased in a gelatin capsule and attached to a flexible wire so that it can be swallowed. recording electrode that used to measure electric potential change in body tissue; for recording, two electrodes must be used, the exploring e. and the reference e. reference electrode an electrode placed at a site remote from the source of recorded activity, so that its potential is assumed to be negligible or constant. stimulating electrode one used to apply electric current to tissue. active electrode Etymology: Gk, elektron, amber, hodos, way an electrode that is applied at a specific point to produce stimulation in a concentrated area in electrotherapy or electrocautery. electrode either of two terminals of an electrically conducting system or cell. 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.

| (43) Although use of the anode as the active electrode was
originally posited by Glass et al, (48) many authors (42-45) have
recently provided persuasive arguments for the use of the cathode. Smaller companies are turning up the heat on the already struggling
large companies by launching specialty instruments such as sheathed
insulated instruments with active electrode monitoring (AEM) that are
capable of preventing stray electric burns. Subjects enrolled in the study were told during the initial
treatment session that although they could expect some discomfort during
procedures involved in removing the dressing, cleansing the wound, and
placing the active electrode in the wound, they should not experience
pain during the course of the 45-minute treatment period. |
