IV Chemical Stress: An intravenous is started . A radioactive substance is given and a picture of the heart muscle at rest is taken. Then Dobutamine is dripped in to increase the heart rate ( instead of walking on a treadmill) . Then another picture is taken of the heart muscle. The pictures are compared. The pictures look like donuts. If there is a bite out of the donut , that means less or no blood is going there.
