1. What would be objective indications of coronary heart disease during a graded exercise test?

The grade exercise test is used by doctors to determine if there is adequate blood flow to your heart during increasing levels of activity, evaluates the effectiveness of your cardiac treatment plan, and determine the likelihood of having coronary artery disease and the need for future testing (see attachment).

4. It is within the "normal" range of functioning for a person's heart rate, blood pressure, breathing rate and perspiration to increase during the test. However, these are objective indicators of possible coronary heart disease when these four factors fall outside the normal range of functioning.
