This test is the same as the EGC but you will also be asked to walk on a treadmill that starts slowly on the level and then gets a bit faster and a bit steeper. Your 'heart trace' will be recorded while you walk on the treadmill. This test helps the doctor decide whether or not it is likely that you have serious narrowing in the coronary arteries. If you have a very abnormal Exercise ECG you may be advised to have a coronary angiogram.
Almost all patients with angina or who have had a heart attack, who can walk comfortably on a treadmill, should have a treadmill Exercise ECG test.
If you cannot manage a treadmill test there are other tests that can give the doctor similar information. These include "Thallium scans" and "Stress Echo tests (echocardiogram)".
