Dobutamine stress echocardiography is a variation of exercise echocardiography to unmask coronary artery blockages. During this test, the heart is stressed by infusing dobutamine. Dobutamine is commonly used to treat patients with low blood pressure, to improve circulation and as a diagnostic testing agent. Dobutamine increases the heart rate and blood pressure and the degree to which the heart contracts. It therefore mimics the effects of exercise for patients who are unable to exercise to a sufficient degree.
The examination starts with the resting transthoracic echocardiogram. After that, dobutamine is infused at a low dose. Following, the dose is increased every three minutes to increase the heart rate and cardiac contractions. At each of these three-minute stages, the heart is scanned using transthoracic echocardiography. An electrocardiogram has to be continuously recorded and blood pressure automatically checked every three minutes.
Disconcerting and stress-related sensations of the patient is to expect during infusion of dobutamine and does not represent any harmful effect. As soon as the infusion is completed, it is discontinued and usually within five to ten minutes the heart rate and blood pressure will return to the levels before starting the exam. Only qualified staff with specific training should perform this test. As for all types of cardiovascular stress testing, all of the necessary equipment and medicines to treat complications must be available in the stress testing room.
