Exercise / Treadmill Stress Testing (GXT)
Stress tests are also called exercise treadmill tests. It is useful for screening high risk populations, preoperative clearance, following patients with known heart disease, or in the diagnosis of chest pain or shortness of breath.
Stress tests are performed by walking on a treadmill at a progressively inclining grade and rate of speed until your heart reaches 85% of the predicted minimum rate and/or until your perceived exertion is greater than your usual activity levels, or until the test shows significant abnormalities. It usually lasts from 30 to 45 minutes. Check with the clinical staff for specific test preparation instructions.
