A blood pressure cuff is placed on one arm. An IV is inserted into a vein on your other arm. Small, round pads are placed on your chest. They will monitor your hearts electrical activity. Your blood pressure and heart rate are monitored before, during, and after you have exercised.

A small amount of radioactive material will be passed into the bloodstream through your IV. The radioactive tracers concentrate in the parts of the heart that have the best blood flow. A special camera will show the parts of the heart that are not getting enough blood. These images are taken while you are at rest and while you exercise.

Your heart may first be monitored while at rest. The exercise or “stress�? part of the test is usually done with a treadmill. You begin by slowly walking on the treadmill. The pace will gradually increase. As you exercise, your heart rate and blood pressure will change. At your peak exercise, the tracer is injected into the IV. You will continue exercising for another one or two minutes so images can be taken.

If you are unable to exercise for any reason, the doctor may use a drug that mimics the effect of exercise on the heart. If you notice any changes in the way you feel, or experience any side effects, notify the doctor who is monitoring the test.

About 15-30 minutes after exercise, you will lie down on a special table. More images will be taken of your heart.

If you have coronary artery disease, you may feel chest pain or angina during the test. You may give you medicine for the symptoms and the test may be stopped early. Let the care staff know if you have any symptoms of jaw, neck, arm, or chest pain.
