A stress echocardiogram ("stress echo") or treadmill test is a non-invasive test that combines ultrasound pictures of the heart with an exercise test. It checks the coronary arteries for narrowing by evaluating muscle function at rest and after exercise. Testing is done in your provider’s office.
Talk to your provider about how best to prepare for your test, if you should continue to talk routine medications and what type of clothing to wear. Fasting from food and beverages before the test may be required.
Typically, electrodes will be placed on different parts of your body to record your heart activity and you will be asked to walk on a treadmill in order to increase your heart rate. A blood pressure cuff will be placed on your arm and inflated periodically to monitor your blood pressure. The length of the stress echocardiogram test will depend on your age and fitness level, but typically it will be 5-15 minutes in length.
If you are not able to exercise, you'll be given medicine that raises your heart rate without physical activity.
If you have any questions about this test, talk to your cardiologist.
