Dobutamine Stress Echocardiogram

A pharmacologic stress echocardiogram (echo) is a non-exercise test used to detect coronary artery disease (CAD), a blockage of blood flow to the heart. The test provides a complete picture of the workings of the heart during periods of rest and exercise.

During the exam, a medicine is given to increase the rate and force of your heartbeat similar to exercise. Then the echo uses high-frequency sound waves (ultrasounds) to look at how the various parts of the heart work. If CAD is present, the stress echo will often note changes in the heart muscle contractions.

Although Dobutamine is the most common drug for this test, other drugs may be used instead. Thus, you may hear this test called a pharmacologic stress echocardiogram when the specific drug is not designated.
