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.

Few items with humans who have studied the electromyographic activity from needle electrodes or fine wire type during swallowing were found.
Jitter analysis with concentric needle electrode in the masseter muscle for the diagnosis of generalised myasthenia gravis.
Specific deviations were as follows 1) switched wires--the signal and detector leads were switched (by unplugging the leads while leaving the needle electrodes in the fish); 2) salt--two cups of seawater (31 practical salinity units) were poured under the fish; 3) conductive board--the fish was placed on a stainless steel conductive board; 4) needle size--the 28 gauge needles were replaced with larger 14 gauge hypodermic needles; and 5) needle depth--BIA electrode needles were placed in the fish in the same orientation as that in the control, except the needles were inserted to a depth of 1 mm rather than 5 mm.
The main advantages of this approach are the freedom to place the needle electrode and transducer wherever needed and the ability to safely and easily treat hard-to-access tumors adjacent to the bowel or gallbladder.
Reference jitter values for concentric needle electrodes in voluntarily activated extensor digitorum communis and orbicularis oculi muscles.
We started this report with a specific treatment planning study to demonstrate the potential for efficiency loss when needle electrodes are used.
In these holes are inserted 10 needle electrodes connected in a short time with the corresponding capacitive storage plate of the GPVCP cascade and through the inductance [L.sub.d][approximately equal to]0.5 [micro]H--with the plate.
(16-19) However, in awake humans, the literature contains only 2 studies that stimulated the ISLN with needle electrodes inserted around the ISLN and induced motor reactions, which were monitored via flexible laryngeal endoscopy and also electromyographic recordings.
For obtaining a standard bipolar lead ECG, needle electrodes were attached intramuscularly in a modified Einthoven lead system.
The electrocardiographic tracings were recorded by needle electrodes in all conscious animals first before and then after drug administration, following every day up to five days.
Its products include subdermal needle electrodes and EEG/PSG (electroencephalography/polysomnograph) electrodes and skin prepping gels.
