About the Test

The goal of the stress test is to have you reach a specific heart rate and the maximum time you can tolerate on the treadmill. During the stress test, you will be asked to walk/run on the treadmill, with speed and elevation gradually increasing as the test progresses. If you experience any unwanted symptoms during the test, you will be able to request it to  be stopped. The test will take approximately 1 hour.

After the Test

Once the test is complete you will be able to drive home. The physician will review the test, and the results will be provided to you at your next appointment or by phone.
