graded exercise test

graded exercise test (GXT)

a test given a cardiac patient during rehabilitation to assess prognosis and quantify maximal functional capacity. The test is given before discharge to determine guidelines for activity programs at home and work during convalescence. See also exercise electrocardiogram.

grad·ed ex·er·cise test

(GXT) (grād'ĕd eks'ĕr-sīz test)
Multistage exercise testing (usually on treadmill or bicycle ergometer) in which exercise intensity is progressively increased (graded) through levels that bring the test subject to a self-imposed fatigue level.
