What Is Dobutamine Stress Echo?
A Dobutamine Stress Echocardiogram is an ultrasounds scan of the heart performed whilst the heart is being exercised. Ultrasound is a very high-frequency sound that you cannot hear, but it can be emitted and detected by special machines to give an accurate picture of the heart muscle, the heart chambers, and structures within the heart such as valves.
The heart is exercise using the drug, Dobutamine, which slowly increases the heart rate in a similar way to the natural increase in heart rate that occurs during exercise. This allows the heart to be imaged at different stages of activity.
