A Stress Test, sometimes called a treadmill 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
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.This test helps determine how your heart works during physical activity. As your body works during any physical exertion, it requires more oxygen and energy. To meet this demand, the heart beats faster and harder. The stress test shows if your heart receives enough blood from its own arteries to work harder, safely.
There may be restrictions as you prepare for this test. Please ask your health care provider.
