Exercise Stress Echocardiogram
What is an exercise stress echocardiogram?
An exercise stress echocardiogram is a test that determines how well your heart and blood vessels are working before and after exercise. Other names for the procedure are echocardiography stress test or a stress echo.
The test involves exercising on a treadmill or stationary bike while your doctor monitors your blood pressure and heart rhythm. During the test, your doctor will take ultrasound images of your heart to determine whether enough blood is getting to your heart muscle or if a narrowing of the arteries is restricting the supply. If you aren’t able to exercise, your doctor may give you an intravenous drug called dobutamine to mimic the effect of exercise on your heart.
Why do I need an exercise stress echocardiogram?
Your doctor may refer you for an exercise stress echocardiography test if you’ve been experiencing any abnormal symptoms such as chest pain, shortness of breath or fatigue. It will provide your doctor with information on how your heart is functioning under stress.
What to expect during an exercise stress echocardiogram
What to expect
- The test usually takes around 30-45 minutes to complete, but please allow up to 1 hour for the entire test, including preparation, imaging, testing and post test observation.
- A cardiac sonographer will attach small metal disks, called ECG electrodes to your chest. These electrodes attach to a machine that monitors your heart rhythm during this test. They will also take your blood pressure. No radiation or X-ray is used.
- A cool gel will be placed on your skin and the sonographer will move a handheld wand across your chest to take the ultrasound images of your heart.
- You will then walk on a treadmill or ride a bike for around 10 minutes. The gradient and speed will gradually increase to make it feel like you are walking uphill. Tell your doctor immediately if you feel unwell or have any chest pains.
- Once you have stopped exercising, the technician will perform another ultrasound.
- You may be asked to hold your breath briefly during the ultrasound.
After the procedure:
- Normal activities can usually be resumed following this test.
- One of our Cardiologists will review the results and provide a full report back to your referring doctor who will contact you for next steps.
