Dobutamine Stress Echo

Patient information:

This test is similar to an exercise stress echo, but is used for people with known or suspected coronary disease who are unable to cope with an exercise test for any reason.

How is it done?

After a resting echocardiogram has been performed an intravenous drip (small plastic tube) is inserted into the arm vein for a Dobutamine infusion.  Dobutamine is a drug that stimulates the heart, mimicking the effects of exercise. Ultrasound images of the heart are taken during the Dobutamine infusion looking for changes that indicate inadequate blood supply to some region of the heart muscle.  The infusion of drug is stopped if any are seen. Dobutamine can be reversed quickly with an intravenous injection of a beta-blocker, if needed. Generally Dobutamine infusion is well tolerated, but it can cause tingling, shakiness, and palpitations.

After the test:

You are asked to stay in the clinic for approximately 20 minutes after the procedure.  The results are interpreted by Dr Kennedy and you are given a full explanation as to the findings and their significance.
