DOBUTAMINE STRESS ECHOCARDIOGRAM TEST

What is a Dobutamine stress echocardiogram test?

• An echocardiogram, also called an echo, is a test that uses ultrasound waves to produce images of the heart.
• A microphone-like device, called a transducer, sends out ultrasound waves that bounce off the heart to produce images of the heart.
• When combined with the administration of the medication, Dobutamine, the echo can detect areas of the heart that are not receiving enough blood flow.
• Dobutamine stresses the heart without exercise.
• Side effects may include sensation of pounding or racing heartbeat, chest pain, facial flushing, or shortness of breath.
• This test is especially useful in identifying blockages in arteries that supply blood flow and oxygen to the heart.

Why has your doctor ordered your stress echocardiogram test?

• Identify cause of chest pain, which can occur with blockages in blood flow to heart.
• Monitor heart function in people with known heart disease.
• Determine response to treatments after angioplasty or bypass surgery, or response to medications.

How do I prepare for a Dobutamine echocardiogram stress test?

• Do not eat 2 hours prior to your test.
• Take your medications on the day of the test unless instructed otherwise.
• Do not apply lotions or powders to the chest.
• Wear loose, comfortable clothing.

What happens during the stress test?

• You will be given an explanation of the test and asked to sign a consent form.
• A nuclear technician inserts an intravenous catheter into your hand or arm.
• Electrodes are placed on your chest and connected by wires to the ECG machine.
• While you lie on an exam table, an echo technician moves a transducer over your chest to obtain images of your heart.
• A nurse supervises the stress portion of the test as the Dobutamine is administered.
• Your blood pressure is checked frequently, and your ECG is continually monitored.
• Echo images are obtained at rest, during and immediately after the infusion of Dobutamine.
• Report any symptoms, such as chest pain, shortness of breath, or dizziness.
• Your blood pressure and ECG will be monitored for several minutes after the test.

When will I know the results of the stress test?

• Final interpretation of the test results is completed by a cardiologist.
• The physician ordering your test and family doctor will receive a report within 3-5 business days.
