These tests are done to determine if your heart is receiving enough blood and oxygen during exercise. They are done while you are exercising because when you are at rest it is harder to detect heart and circulatory problems.During the test you will exercise by walking or running on a treadmill while your heartbeat and blood pressure are measured. Tests are performed by a staff member who specializes in this area of testing, and under the supervision of a heart doctor (Cardiologist).
