  • Im actually having one of these done next week. Its not an invasive procedure. Basically,they inject dye so they can take pics of your heart resting and then you walk on the treadmill and they take more pics to see how your heart does under stress.

    Nuclear stress test: This test helps to determine which parts of the heart are healthy and function normally and which are not. A very small and harmless amount of radioactive substance is injected into the patient. Then the doctor uses a special camera to identify the rays emitted from the substance within the body; this produces clear pictures of the heart tissue on a monitor. These pictures are done both at rest and after exercise. Using this technique, a less than normal amount of thallium will be seen in those areas of the heart that have a decreased blood supply.
