Nuclear Stress Test

Nuclear stress testing is a diagnostic test to determine heart function and if the heart muscle is receiving adequate blood supple. There are two parts to this test, rest and stress.
CARDIOLITE will be injected into your vein while you are at rest, and a special camera will take pictures of your heart.
The stress test portion of the test is performed on a treadmill or the use of chemicals (Persantine or Dobutamine) with continuous EKG monitoring. CARDIOLITE will be injected during exercise or after the injection of chemicals and another set of pictures will be taken of your heart.
