A cardiac stress test (also called a graded exercise test) measures the electrical activity of the heart during exercise. You will be asked to walk on a treadmill (or pedal on a bike) while your heart rhythm and blood pressure are monitored. The treadmill speed and slope (incline) will increase throughout the test. It is important to exercise for as long as possible and report any symptoms that you may experience during exercise.
There are different types of stress tests that may be done. Please confirm the test you are having with your Health-Care Provider as they may be done in different locations and have different instructions to prepare for the test.
