A stress test, sometimes called a treadmill test or nuclear stress test, helps determine how well the heart handles work. As the patient walks on a treadmill or is given medication to stress the heart, an EKG machine monitors the heart rate, breathing, blood pressure, the electrical activity of the heart, and exercise tolerance. With a nuclear stress test, there are two parts to the test: a resting study and a stress study.
A Nuclear Stress Test is used by doctors to diagnose and monitor heart disease.
- During a Nuclear Stress Test, a safe amount of a radioactive drug is injected into your vein which allows the cardiologist to see how well blood is flowing to and through your heart.
- The test, usually conducted over two days, consists of taking images of your heart in two phases: a stress phase and a resting phase.
There may be restrictions as you prepare for this test. Please ask your health care provider.
