During the test, your nerve is stimulated, usually with electrode patches attached to your skin.A nerve conduction velocity What is nerve conduction velocity? Also called an electroneurography, EneG, or nerve conduction study, a nerve conduction velocity (NCV) test is a measurement of the speed of conduction of an electrical impulse through a nerve.
