Dobutamine Stress Echocardiography (Echo)
This type of echocardiogram uses the drug dobutamine and harmless sound waves to help see if any blood vessels in your heart are blocked. This test is often done in a hospital or cardiac testing center.
Before Your Test
Mention what medicines you take and ask if you should take any before the test. Don’t eat, smoke, drink alcohol, or have any caffeine for
During Your Test
Small pads (electrodes) are placed on your chest to record your heartbeat.
An intravenous (IV) line is started in your arm.
A painless device (transducer) coated with cool gel is moved firmly over your chest. This device creates sound waves that make images of your heart on a screen.
Dobutamine is then slowly given through the IV. It is normal to feel your heart pound for a few minutes.
Echo images are taken while you feel the effects of the drug and after your pulse returns to normal. You may be given a second drug to slow your heartbeat to a normal level.
Your heart and blood pressure are monitored during and after the test.
After Your Test
When the test is over, you may return to your normal routine. Ask your doctor about taking any medicine that you were told to skip before the test.
