An exercise stress test is a screening tool used to test the effect of exercise on your heart. This test is done at a medical center or health care provider's office.

The technician will place 10 flat, sticky patches called electrodes on your chest. These are attached to an ECG monitor that follows the electrical activity of your heart during the test.

You will walk on a treadmill or pedal on an exercise bicycle. Slowly (usually every 3 minutes), you will be asked to walk (or pedal) faster and on an incline. It is like walking fast or jogging up a hill.

While you exercise, the activity of your heart is measured with an electrocardiogram (ECG), and your blood pressure readings are taken.
