Adenosine myoview
Adensoine Myoview Test
What is Adensoine Myoview Test?
An Adenosine Myoview is ordered when you are unable to exercise on a treadmill for any reason.
Adenosine myoview test is used to evaluate blood flow to the heart. During the test, a small amount of radioactive tracer is injected into a vein. A special camera, called a gamma camera, detects the radiation released by the tracer to produce computer images of the heart.
Combined with a medication, the test can help determine if there is adequate blood flow to the heart during activity versus at rest. The medication, Adenosine, does not increase your heart rate, instead, it dilates blood vessels leading into the heart, increasing blood flow, therefore simulating exercise for patients unable to exercise on a treadmill.
Procedure
The first part of the procedure will take approximately 2 hours. You will have electrodes placed on your chest that will allow us to monitor your heart rhythm during the test.
An intravenous line (IV) will be started in your arm and an injection of a Radioisotope, also called a radioactive tracer, will be given. This tracer is a safe, low-level radioactive substance that travels through the blood stream to the arteries that supply blood to the heart. Approximately 45 minutes later, you will be placed under a special camera or scanner to visualize the radioactive tracer and obtain the first set of images of your heart.
Next, a medicine called Adenosine will be injected through your IV that will cause your heart rate to increase, similar to that of walking on a treadmill.
After receiving Adenosine you will be allowed to leave the office to eat lunch. Approximately 3 hours later you will return to the office for the final set of images, which will take approximately 15 minutes. There are no driving restrictions before or after the test.
