An exercise tolerance test (ETT) is the same as an electrocardiogram (ECG) but recorded while you are exercising.
This test assesses how well your heart works when you are doing something active. During exercise, your heart needs more blood and oxygen and is therefore working harder.
The test will show if there is a lack of blood through the arteries that supply the heart.
