| blood gas monitoring, transcutaneous | The noninvasive measurement or determination of the partial pressure (tension) of oxygen and/or carbon dioxide locally in the capillaries of a tissue by the application to the skin of a special set of electrodes. These electrodes contain photoelectric sensors capable of picking up the specific wavelengths of radiation emitted by oxygenated versus reduced haemoglobin. (12 Dec 1998) |
|---|---|
| cardiac pacing, artificial | Regulation of the rate of contraction of the heart muscles by an artificial pacemaker. (12 Dec 1998) |
| pacing catheter | A cardiac catheter with one or more electrodes at its tip which can be used to artificially pace the heart. (05 Mar 2000) |
| transcutaneous | <pharmacology> Entering through the dermis or skin, as in administration of a drug applied to the skin in ointment or patch form. (17 Mar 1998) |
| transcutaneous electric nerve stimulation | Electrical stimulation of nerves and/or muscles to relieve pain; it is used less frequently to produce anaesthesia. The optimal placements of electrodes or "trigger points" may correspond with acupuncture analgesia points. Tens is sometimes referred to as acupuncture-like when using a low frequency stimulus. (12 Dec 1998) |
| underdrive pacing | Electrical stimulation of the heart at a rate lower than that of an existing tachycardia; designed to capture the heart between beats, i.e., to interrupt a reentry pathway in order to terminate the tachycardia. (05 Mar 2000) |
