gradÂ·ed exÂ·erÂ·cise 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. See: stress test, Astrand-Ryhming Cycle Ergometer Test.
During the test the patient's various symptoms and blood pressure response is repeatedly checked. When using the ECG and the blood pressure monitoring by itself the test is called a cardiac stress test or an exercise stress test.Besides these, the test is also called as an exercise treadmill test or an exercise tolerance test or a stress test or an exercise ECG test.hen it is compared to the blood flow that occurs during rest, the stress test reflects the imbalances of the blood flow to the individual's heart in particular the left ventricular muscle tissue. This is the part of the individual's heart that helps perform the largest amount of the work in pumping blood.
