Nuclear Stress Test

  1. Exercise Nuclear Stress Test:

This test is very similar to a treadmill stress echocardiogram. Instead of resting and stress images taken by an ultrasound machine, they are taken using a nuclear medicine machine.

  1. Lexiscan (resting) Stress Test:

Instead of using a treadmill to reach target heart rate, an IV will be started to inject a small amount of radioactive material (tracer), called Lexiscan. This flows through your body and allows us to better see the heart muscle.  Resting images will then be taken before the stress portion. After the resting images, an injection of medicine to will make your heart work like your body is undergoing physical activity. A second set of pictures, the “stress images”, will then be taken.
