Dobutamine Stress Echocardiogram

What is a Dobutamine Stress Echocardiogram?

A Dobutamine Stress Echocardiogram (DSE) is a non-invasive medical test used to assess the heart’s function while it is under stress, as an alternative to exercise stress. The test is usually performed to diagnose or monitor heart conditions such as coronary artery disease and heart valve problems, and for preoperative cardiac assessment.

DSE involves the administration of Dobutamine, a medication that mimics the effect of exercise on the heart, via an intravenous cannula. During the test, an echocardiogram, which uses high-frequency sound waves to produce images of the heart and its surrounding structures, is used to produce images of the heart at rest, and again during various stages of the test, as the dose of Dobutamine is gradually increased. The images are used to evaluate the blood flow to the heart and the functioning of the heart’s valves.

DSE typically takes about 45 minutes to an hour and is performed with the patient lying on an echocardiography table, while connected to an electrocardiogram (ECG) and automatic blood pressure monitor. 

If any abnormalities are detected, further testing may be recommended to determine the cause of the problem.

There is no specific preparation required. Ladies, please try and wear a top and bottom rather than a dress. A bare chest is required for the test, but a gown will be available for modesty.

DSE is a safe and effective way to assess heart function, but as with any medical test, there is a small risk of complications, which you will have the opportunity to discuss, along with other concerns you may have, before the test is performed. You will also be provided instructions for preparation, including appropriate clothing, or withholding certain medications prior to the test.
