Drug Induced Stress Test Echocardiogram with Dobutamine

This test evaluates your heart’s response to exercise and records your heartbeat even though you are not actually exercising. Since you may be physically unable to exercise to increase your heart rate, you will be given the drug Dobutamine, which causes the heart to gradually beat faster and stronger to simulate exercise.

An echocardiogram uses sound waves to see images of the heart muscle, valves and function of the heart. A special instrument called a transducer is held on the chest and picks up sound waves and uses them to project a picture of the heart on a screen. A recording is made for the cardiologist to review at a later time.

The test will take approximately 90 minutes.

Preparation

To ensure accurate test results, follow all instructions given by your physician, including:

1. Do not eat, drink or use tobacco products for four (4) hours prior to the test. If you have diabetes, ask your doctor what you may eat before the test.
2. Do not eat or drink products that contain caffeine for six (6) hours prior to the test. See the list on the back of this brochure for the most common foods and products that contain significant amounts of caffeine.
3. Bring a written list of the prescription and non-prescription medications you are currently taking. We’ve provided a space in this brochure to list them. Include over-the-counter medications and herbal remedies.
4. Check with your doctor before taking medications the day of your test. Some medications belonging to the “Betablocker” family may interfere with the test. Your doctor will advise you whether this applies to you - and whether you should take that medication prior to your test.
5. Wear comfortable clothing.
6. You may drive yourself and arrive unaccompanied for the test.

What happens during the test?

A cardiologist will be present to monitor your test. You will be asked to replace your shirt or blouse with a hospital gown. An intravenous (IV) will be started to administer the Dobutamine. The images will be taken while you are in a resting position, lying on your left side. A clear gel is applied to the transducer to allow it to glide easily across your chest. The transducer will be pressed against your chest and moved in many positions. At times, you may experience slight pressure. Two sets of images will be taken; one set while the heart is at a resting rate, and one set after the Dobutamine is administered. Please advise us if you are feeling any discomfort or anxiety during the test.

When the test is complete

The cardiologist will study and interpret the images, and will report them to your doctor.

You may go back to your normal diet and activities unless instructed otherwise by your doctor.

Test results
