A Dobutamine Stress Echocardiogram, or Dobutamine Stress Echo, is used to evaluate your heart function when it is “stressed.” In this case, because you may not be able to walk on a treadmill or exercise long enough to “stress” your heart, you will be given a medication to make your heart beat faster and stronger. We use ultrasound images before, during and after you receive this medication to help your doctor look at your heart function.
WHAT TO EXPECT DURING THE TEST:
An IV (intravenous) line will be started in a vein in your arm to give you the dobutamine medication. During this time an electrocardiogram (EKG) will measure the electrical activity of your heart. You may feel a mild headache, shaky, and warm or flushed when the dobutamine is being given. You will also feel your heart start to beat faster and harder; this is normal.
This test takes approximately two hours. You will be asked to stay for approximately 30 minutes following the test to assure you do not have any problems such as chest pain, shortness of breath, nausea, pain into your jaw or back and/or dizziness.
AFTER THE TEST
Should you experience chest pain or pressure, shortness of breath, nausea, pain into your jaw or back, or dizziness, please call your doctor and 9-1-1.
