Exercise testing is usually done when coronary artery disease is suspected. It is used to assess the function of the heart when it is put under stress. The test involves raising your heart rate by exercising, generally using a treadmill with an adjustable slope or an exercise bicycle, and monitoring the heart’s function. The exercise is tailored to ensure that your heart is tested adequately without putting you at risk. Various monitoring methods may be used, including radionuclide scanning, which can image the heart’s function, and ECG, which monitors the heart’s electrical activity.
