My primary care physician is sending me for a cardiac
stress test. I was debating on whether I should ask for a cardiopulmonary
stress test instead. I have difficulty breathing and shortness of breath. Also, I have low blood oxygen (High Hemoglobin and High Hematocrit) and low carbon dioxide. I know the cardiopulmonary stress test measures gas exchange during exercise. I just don't want to have to do both tests at some point, if there is nothing wrong with my heart.
