Exercise Stress Test

A stress test, sometimes called a treadmill test or exercise test, helps a doctor find out how well your heart handles work. As your body works harder during the test, it requires more oxygen, so the heart must pump more blood. The test can show if the blood supply is reduced in the arteries that supply the heart. It also helps doctors know the kind and level of exercise appropriate for a patient.

A person taking the test is hooked up to equipment to monitor the heart, then walks slowly in place on a treadmill. The speed is increased for a faster pace and the treadmill is tilted to produce the effect of going up a small hill. You may be asked to breathe into a tube for a couple of minutes. And you can stop the test at any time if needed. Afterwards you will sit or lie down to have their heart and blood pressure checked. Heart rate, breathing, blood pressure, electrocardiogram, and how tired you feel are monitored during the test.

Healthy people who take the test are at very little risk. It's about the same as if they walk fast or jog up a big hill. Medical professionals will be present in case something unusual happens during the test.
