Cardiopulmonary exercise test

Some hospitals may also ask you to do a cardiopulmonary exercise test. This test analyses the efficiency of the heart muscle by measuring the amounts of oxygen your body uses during exercise. You will be asked to breathe into special equipment while you are exercising (like the exercise test). If the efficiency of your heart is low, this may suggest that you have cardiomyopathy (inefficient pumping action of the heart).
