What is a Stress Echocardiogram?

This test combines walking on a treadmill with ultrasound images of the heart. Sound waves, called ultrasound, produce images of the heart’s structure and movement. Ultrasound images are obtained before and after exercise. By comparing the images, your doctor is able to evaluate the function of your heart.
Alternative Names: Stress Echo

If you are unable to exercise on a treadmill, you will be given a medication called Dobutamine, which is given through an intravenous (IV) line. It mimics the effects of exercise on the heart by increasing the heart rate.

Why is the test done?

To evaluate the causes of chest discomfort or other symptoms that may be related to the heart.

How do I prepare for this test?

• Wear a two-piece, loose-fitting outfit and comfortable walking shoes.
• Follow your doctor’s instructions for eating and drinking prior to the test.
• If you are taking heart medications, check with your doctor. He or she may ask you to delay certain medications until after the test.
• Ingesting caffeine or smoking may affect your test results. Follow your doctor’s instructions.

How long will it take to complete the test?

A stress echocardiogram requires about two (2) hours to complete.
