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.
