DOBUTAMINE
SPECT RADIONUCLIDE STRESS TEST
WHAT IS A DOBUTAMINE SPECT RADIONUCLIDE STRESS TEST?
A Dobutamine Radionuclide Stress Test is an examination during
which your heart rate, heart rhythm, blood pressure and EKG
are evaluated, alone with actual imaging of the heart muscle.
Cardiolite and/or Thallium, a mild radioactive substance given
in small amounts, is what allows us to obtain these images of
your heart. There are no side effects to either of these
isotopes.
WHY IS A DOBUTAMINE SPECT RADIONUCLIDE STRESS TEST NECESSARY?
A Dobutamine SPECT Radionuclide Stress Test is a more accurate
way of evaluating the condition of the heart muscle and its
blood supply.
WHO WILL DO THE TEST?
A cardiologist, a nuclear medicine technologist, and a cardiac
nurse or technologist will be present for the test.
WHAT IS THE USUAL PROCEDURE?
Take all
of the medications as you normally would and bring a list of
those medications to the test.
Avoid caffeine and decaffeinated products for 24 hours prior
to the test. On the day of the test eat a light meal, avoid
dairy products and do not smoke for two hours prior to the
test. When you arrive at Consultants In Cardiology,
Inc., please report to the receptionist in order to complete
the registration forms. If you wear glasses, bring them, as
you will be asked to read and sign a consent form.
WHAT DOES THE EXAMINATION INCLUDE?
A brief cardiac history will be taken and an IV will be
started in your arm. A Radionuclide will be injected into the
IV and a 15 minute resting image of your heart muscle will be
taken 30 minutes following the injection. Following the
resting image, a simple skin preparation will be done and
electrodes applied to monitor your heart. The Dobutamine will
be administered over approximately 15 minutes. When an
appropriate heart rate has been reached a Radionuclide will be
injected into the IV. We will have you rest for approximately
30 minutes and a stress image will be taken of your heart
muscle. This image will take about 15 minutes. Please allow
two hours for your total exam. Your cooperation is vital to
the successful completion of this test. If you have any
further questions, please feel free to ask your nurse or
physician.
