Electro-oculography: EOG. A type of electrophysiologic retinal testing done to assess the function of the retinal pigment epithelium by measuring change in the electrical potential between the front and back of the eye in response to dark and light.
A recording of the electrical activity of the heart. Abbreviated ECG and EKG. An ECG is a simple, noninvasive procedure. Electrodes are placed on the skin of the chest and connected in a specific order to a machine that, when turned on, measures electrical activity all over the heart. Output usually appears on a long […]
Electrocoagulation: A procedure that uses an electrical current to stop bleeding.
Electrocochleography: A test that measures the electrical potentials generated in the inner ear in response to stimulation by sound. Electrocochleography may be done, for example, to confirm the diagnosis of Meniere disease. Abbreviated ECochG (or ECoG).
- Electroconvulsive therapy
The use of controlled, measured doses of electric shock to induce convulsions. Convulsions so induced can sometimes treat clinical depression that is unresponsive to medication. Abbreviated ECT.
A technique for studying the electrical currents within the brain. Electrodes are attached to the scalp. Wires attach these electrodes to a machine, which records the electrical impulses. The results are either printed out or displayed on a computer screen. Different patterns of electrical impulses can denote various forms of epilepsy. Abbreviated EEG.
