These tests show whether your heart pumps normally during stress.  They also show whether arteries can meet an increased demand for blood.  To prepare for the test, you may exercise on a treadmill to increase the heart rate.  Or medication may be used to stress the heart.

• An Echocardiogram uses sound waves to show the structure and movement of the heart.

• With Nuclear Imaging, a small amount of weakly radioactive material is injected into a vein.  The material is absorbed by the heart.  This enables a scanning camera to take pictures of blood flow through the heart muscle.
