What Is a Dobutamine Stress Test?

The dobutamine stress test is a kind of echocardiogram, according to ClevalandClinic.org. Dobutamine, a drug administered intravenously, stimulates your heart to mimic its behavior during physical activity, and the echocardiogram is taken to monitor its activity. This gives doctors a graphic representation of your heart's response to stress.

Reasons

• This test may be administered to monitor how your heart reacts to stress, according to the Cleveland Clinic. It may also be used to monitor heart valve function or check for signs of heart disease.

Preparation

• Do not eat or drink for four hours before the test. Ask your doctors which of your medications are safe to take before the test, as some medications could affect the results.

The Test

• Electrodes will be put on your chest to monitor your heart. Dobutamine will be administered, which will make your heart speed up, and doctors will monitor your heart's activity.

Side Effects

• Dobutamine may cause nausea and shortness of breath, according to the Carandolet Health Institute. Increased heart rate during the test may cause a slight headache.

Warning

• Ask your doctor what you should do before the test if you are diabetic. Do not skip a meal before the test.

Note

• This type of test is normally used only for disabled individuals who are physically unable to increase their heart rate through exercise.
