Exercise tolerance test

An exercise tolerance test is an ECG carried out while the patient exercises on a treadmill.

Chest pain or other symptoms during exercise may suggest angina, a specific type of pain caused by coronary heart disease. An exercise ECG can therefore help to diagnose coronary heart disease. For patients known to have this condition, it can give more detailed information about the severity of the illness and help to establish a treatment regime. The test usually takes about half an hour, beginning at a very slow speed and gradually made harder by increasing the speed and incline of the treadmill. The ECG reading will be monitored constantly and readings will continue to be taken in the recovery period after exercising. The test can be stopped at any time if you develop any chest pain, breathlessness or fatigue. You should make sure that you are wearing comfortable clothing and shoes suitable for exercise.

The ECG above shows typical abnormalities in a patient with angina.
