What is an exercise tolerance test?
This is an examination to find out how your heart will respond under stress. This is important to know if you are having major surgery.
You will be asked to walk on a treadmill while some basic readings of your heart are made. The test starts off at a very easy rate and is gradually made harder by increasing the speed and slope of the treadmill. The test lasts for about 15 minutes. If you have pains in your chest or become breathless, the tests will be stopped.
