Cardiac Stress Tests
What Is a Cardiac Stress Test?
A cardiac stress test helps you and your doctor learn more about how your heart is working. A cardiac stress test with images use a radioactive tracer that enters your heart to show blocked arteries or other damage. It allows us to take images of blood flowing in your heart. We take images of your heart at rest and after your heart rate has increased. The exam takes about two to three hours.
A cardiac stress test with images is a type of nuclear medicine exam.
A Note About TracersWe use the lowest dose of radioactive tracer to get the highest quality images. The radiation risk is very low compared to potential benefits.
Types of Stress Tests

Stress Test with Medicine and Images
- Instead of making your heart pump harder with physical exercise, we give you a medicine that makes your blood flow like it does while you exercise. We give you this medicine along with a radioactive tracer through a thin tube inserted in your arm (an intravenous or IV line).
