Dobutamine Stress Echocardiogram

How Is It Done?

You will have several electrodes (small sticky patches) placed on your chest. An intravenous (IV) is started in a vein in your arm. A small wand (called a transducer) is placed on your chest to take pictures/images of the heart. These pictures are shown on a screen.

A cardiologist (heart doctor) will be with you for this part of the test and will be able to see any abnormalities.

The Dobutamine is given slowly through the intravenous (IV) for about 15 to 20 minutes. The wand will be used during the test. It is normal for the heart muscle to squeeze faster and harder while getting the Dobutamine. You may also be given a medicine called Atropine to help increase your heart rate. The cardiologist will use the ECG electrocardiogram) and echocardiogram to assess the pumping function of your heart. When your heart has reached a certain rate and the doctor has enough information the Dobutamine will be stopped. You will continue to be monitored until your heart rate returns to your normal level. The test is then complete.
