DOBUTAMINE STRESS ECHO (ECHOCARDIOGRAPHY)
What is the test?
Stress echocardiography is a special examination that uses ultrasound waves to image
the heart and evaluate its function both at rest and with the added "stress" of
increased heart rate and blood pressure.
What preparation is needed?
You will need to be without food for 2 hours prior to the procedure. If you are
scheduled for late morning or afternoon, a light breakfast is permitted. You may take your
regular medications at their usual time with a small amount of water. If you have specific
medication questions, please call and talk to one of our nurses. Please dress so you can
remove all clothing from the waist up. A cover gown will be provided. There will be some
skin preparation done with special equipment to "rough up" the skin to ensure
that the EKG patches stay on during the test.
How is the test done?
To induce the "stress" of increased blood pressure and heart rate, you will
have a medication called dobutamine administered through an intravenous (IV) line. This
will slowly increase your heart rate and blood pressure in a controlled setting while
being constantly monitored by specially trained medical personnel and a trained
cardiologist. Baseline EKG and Echo images are obtained for comparison during the test,
and these will be continuously monitored throughout the medication infusion as well. It is
expected that it will give you a slight headache, feelings of nausea, anxiety, or tremors.
You will be closely monitored for any signs of angina (chest pain), problems breathing, or
irregularities of rhythm of your heart. The test should take about 1 hour to complete, but
due to the need to preregister, attach and set up the equipment, please plan on 2 hours
for the completion of this exam from the initial check-in time.
What can I expect after the test?
You will be able to return to your normal activities after the test. You may want to
bring someone with you to drive you home, as the medication effects may leave you feeling
weak.
