Dobutamine Stress Echocardiogram (DSE)

What is a Dobutamine Cardiolyte Stress Test?   

• This is a test that can be done on patients that cannot exercise on a treadmill.
• Dobutamine is a medication that increases heart rate and contractility, similar to the effects of exercise.
• This helps the doctor determine if the heart is getting an adequate supply of blood and oxygen when it is working harder.
• The procedure includes an echocardiogram done at rest, and again at peak heart rate. This procedure is a noninvasive test that uses ultrasound ( sound waves) to evaluate the structures of the heart, and how well the heart is working.
• As the patient is positioned on their left side, warmed gel is applied to the chest and a wand – like device called a transducer is moved over the chest to produce images of the heart and it’s structures.
• Electrodes are placed on the chest to record EKG’s before, during, and after the test. This records the heart rate and rhythm.
• A Registered Nurse starts an I.V. through which the dobutamine is given.
• A cardiologist is present for this test and observes the patient for any symptoms, as well as their EKG, blood pressure, and echo images.
• Preparation and the actual test take about 90 minutes.
• This test must be ordered by a doctor and be scheduled.

Why is a Dobutamine Stress Echo done?

• This test will help the doctor evaluate the patient’s cardiac status related to:
  • If the patient has had any heart attacks in the past.
  • If any symptoms develop and at what heart rate.
  • Irregular heart rhythms.
  • If there is an adequate blood and oxygen supply to the heart at rest, and when it is working harder.
  • The size, appearance, and efficiency of the heart’s valves and chambers.

What Preparation is Needed?
