Exercise Isotope Study

Approximate time - 2 3/4 to 4 hours

This is a specialized test for diagnosing heart abnormalities. An IV will be started in your arm to allow injection of medication. A radioactive isotope will be injected through the IV and pictures will be taken of your heart during the test.

For the next portion of the study, a technician will attach electrodes to your chest. They will be connected to an EKG machine, which monitors heart rate and rhythm. You will be asked to jog on a treadmill until your heart reaches an 85% maximum predicted heart rate (calculation based on age, weight and other variables). Your physician may attend this portion of the test. Once your heart rate has increased, more isotopes will be injected through the IV and additional pictures of your heart will be taken.
