Cardiac Diagnostic Tests


Exercise Stress Test (EST)

For this test you will be monitored walking on a treadmill. The speed and incline of the treadmill will increase gradually as the test progresses. The purpose of this test is to see how your heart responds to exercise. You should not eat, drink or smoke for two hours prior to this test. Please ensure you wear comfortable and  appropriate clothing and footwear such as trainers.
