Swelling. Swelling (edema) is a build-up of water in the tissues. This can be caused by retaining salt and water due to medicines or heart, liver, or kidney failure. It can sometimes be due to poor nutrition, pelvic tumors, or a blockage in the veins or lymph system.
Reactance, denoted X, is a form of opposition that electronic components exhibit to the passage of alternating current (alternating current) because of capacitance or inductance. In some respects, reactance is like an AC counterpart of DC (direct current) resistance.
Electrocochleography (ECOG) Electrocochleography (ECOG) is a diagnostic test that examines the function of the inner ear. This test measures the electrical potentials generated in the inner ear in response to sound. The ECOG is most often used to determine if the inner ear has an excessive amount of fluid pressure, which can cause symptoms such as hearing loss, aural fullness, dizziness, and/or tinnitus. These symptoms are sometimes indicative of certain ear pathologies such as Meniereâs disease or endolymphatic hydrops.
