Dobutamine Stress Echo Test Information:
This test evaluates how wel your heart contracts at rest and as your heart rate
increases from receiving the medication Dobutamine. An IV (intravenous) catheter wil
be started to administer the medication, which wil elevate your heart rate as if you were
exercising. Dobutamine is given to increase your heart rate to a desired level that is
determined by your age. Ultrasound images are taken before, during, and at the end of the test. Your blood pressure and heart rhythm (EKG) wil be monitored throughout the test.
