What To Expect During Your Test

  • When you arrive for your test, wear comfortable clothing.
  • The exam will be explained to you and you will be required to sign a consent form. Please do not hesitate to ask any questions.
  • An IV will be placed in a vein in your hand or arm. The IV will be used to inject an isotope two times during the procedure. If the type of test ordered for you is a non-walking chemical stress test an additional injection of medication will be given to stimulate stress.
  • Sestamibi (Cardiolite) is the first isotope to be injected through the IV.  It will be necessary to wait 15-20 minutes before the resting images can begin.  You will then lie down on an imaging table with your left arm, or both arms if possible, above your head.  The imaging camera will move slowly around your chest for approximately 15 minutes.
  • Once the resting images are completed, EKG electrode pads will be placed on your chest to monitor your heart during the stress portion of your test.
  • Blood pressure and EKG tracings will be monitored throughout the stress testing.
  • The type of stress testing depends on what your doctor has ordered.  You will either walk on the treadmill, or lie on exam table and be given a medication to simulate stress.
    • Treadmill:  You will be exercising on an electric powered treadmill. As you walk, the speed and incline will increase at selected intervals during the test, until you reach your target or peak level.  The length of the exercise test depends on you and how you are feeling.
    • Lexiscan or Persantine:  Medicine is given through your IV over 4 minutes. You may be asked to do simple exercises to help circulate the isotope. You may also be given medication to reverse any effects of the Lexiscan or Persantine.
  • At the appropriate time, during the stress, cardiolite (the second isotope) will be injected into the IV.  At the conclusion of the stress portion of the test, a waiting time of 30-60 minutes is required before the stress images can begin.
  • Taking the stress images will be identical to the resting images, however a heart monitor will be connected during the 15-20 minute scan.
  • At the conclusion of the test, the IV will be removed.  You may return home to your normal activities and medication routine.
