Exercise Stress Test
Description: Why is this test ordered?
This test is done to evaluate the working capacity and function of your heart. You'll walk on a treadmill while the speed and grade are gradually increased, until a supervising doctor or nurse practitioner feels a sufficient amount of information has been obtained.
How long will this test take?
This test will take approximately one hour.
Prior to the test: What do I need to do?
Do not eat, drink or smoke for at least three hours before your test. It is OK to drink water. Take all of your medications as usual unless otherwise directed by your doctor. Bring a current list of your medications with you.
* If you have diabetes, try to have a light meal or snack three hours before your test, as exercise tends to lower blood sugar. And check first with your doctor if you take insulin or other medications for diabetes. If you have a blood glucose meter, it is useful to check your blood sugar before coming for the test.
What should I wear?
Wear comfortable well-fitting shoes; sneakers are recommended. Clothing should be loose fitting and comfortable for exercising. Women should wear a bra.
Day of the test
When you arrive at the testing, one of the technicians will take a brief history, including the medications you take. You will then be monitored with electrocardiogram and blood pressure machines. The electrocardiogram will record your heart's electrical activity throughout the test. You will walk on the treadmill with the speed and grade increasing every three minutes. A safe maximum heart rate has been established for your age. You will walk until you reach 90% of this rate, or until you feel tired or the supervising cardiologist or nurse practitioner feels you should stop. Because this may be more exercise than you normally do, it is natural to feel short of breath, and for your legs to become tired. When you finish the exercise, you will rest in a recliner and more electrocardiogram readings and blood pressures will be taken.
Results of the test
The test will be interpreted by a cardiologist, who will then send the results to your referring physician. Results will not be available to you the day of the test.
