A stress test enables a physician to learn how well your heart works during exercise. This may also be called an exercise test or a treadmill test. Physicians use exercise stress tests to determine a safe level of exercise or diagnose heart-related problems. The test can help a physician diagnose coronary artery disease, determine the cause of chest pain, light-headedness or dizziness.
During the test, the patient is hooked up to heart-monitoring equipment and walks on a treadmill. The speed and incline is gradually increased. While taking the test, the patient’s heart rate, blood pressure and heart rhythm are carefully monitored.(1)
