Exercise ECG Test
Also called: Cardiac Stress Test, Treadmill Test, Graded Exercise Test

What is an Exercise ECG Test?

• An exercise ECG test allows the doctor to learn how well the heart functions when it is made to work harder. This test can help detect a heart problem that may not be apparent at rest. 

• The exercise ECG test is done while walking on a treadmill. During the test, an electrocardiogram (ECG or EKG) records the electrical activity of the heart. 

What is the purpose of this test? 

• Even if the heart functions well at rest, the blood supply to the heart may not be sufficient to meet its needs when its workload is increased. The exercise ECG test is used to see how well the heart functions during exercise.

• Look for abnormal heart rhythms that may develop during exercise. 

• Determine the level of exercise that is right for your child. 

• Evaluate the cause of chest pain. 

What happens during the test? 

• The exercise ECG test is generally performed at a hospital or a doctor's office. 

• A nurse or technician will show your child how to walk on the treadmill. The speed and incline of the treadmill will increase slowly. 

• Your child's blood pressure will be checked every few minutes, and the ECG will be carefully monitored for abnormal changes. 

• The test continues until your child reaches a "target" heart rate. (based upon your child's age) The test may end if your child has significant symptoms or becomes too tired to continue. Other times, the test may be stopped when sufficient information has been obtained. 

• Your child will be helped to a chair or bed when the exercise portion of the test is over. Your child's blood pressure and ECG will be monitored for another 5-10 minutes 

• The exercise portion of the test usually lasts for 5-15 minutes. However, allow about an hour for the entire test. 

When will I know the results of the test? 

• The doctor will discuss the test results with you before you leave.
