Cardiac Stress Test. You have been referred by your physician for a stress test--an exam which shows how well your heart works during physical activity. The exam can be used to measure the blood flow to the heart as well as to see any areas where the heart has been damaged (such as by a heart attack). The test measures blood flow to the heart muscle both at rest and during stress on the heart.
