What is an isotopic study?
If the exercise test is abnormal, may be indicated isotope study of the heart, which is very accurate, easy to make non-invasive (ie, painless and without punctures) and does not require hospitalization. The radiation received is low and can be more complicated eviitar other tests such as cardiac catheterization (coronary angiography).
Thallium exercise test
It involves injecting a small dose of radioactive isotope into a vein, during an exercise test on treadmill. A special device records a series of images of locations in the heart of the isotope. The dark areas indicate parts of the heart where it is less blood flow. It provides information on the exact location of the blocked artery.
Heart scan (isotope angiogram)
It is a variant, which received an injection of isotope into a vein and then you lie on an exercise table with his feet on the pedals of a bicycle.
