What happens before a dobutamine stress echocardiogram?

A dobutamine stress echocardiogram is a diagnostic procedure that may be used when a physician wants to assess the heart muscle under stress. If exercise on a treadmill is not an option (too much stress on the heart) due to a person's medical condition, a physician may use an intravenous medication called dobutamine. Dobutamine causes the heart to beat faster and will mimic the effects of exercise on the heart.

The following steps are taken before the procedure:

• Your physician will explain the procedure to you and offer you the opportunity to ask any questions that you might have about the procedure.
• You will be asked to sign a consent form that gives your permission to do the test. Read the form carefully and ask questions if something is not clear.
• Notify the physician if you are allergic to or sensitive to medications or latex.
• Fasting may be required before the procedure. Your physician will give you instructions as to how long you should withhold food and/or liquids. In some cases, cigarettes and caffeinated beverages, such as coffee, tea, and cola may be restricted several hours before testing.
• If you are pregnant or suspect that you may be pregnant, you should notify your physician.
• Notify your physician of all medications (prescription and over-the-counter) and herbal supplements that you are taking.
• Notify your physician if you have a pacemaker.
• Based upon your medical condition, your physician may request other specific preparation.
