The graded exercise test can be used for both diagnosis and functional assessment. Indications for diagnostic testing include pain, palpitation, elevated systemic blood pressure and potential problem. Functional testing is performed to determine prognosis, progression of cardiac disease, post-therapy status and physical fitness. For the diagnostic study, medications other than sublingual nitroglycerin should be avoided. For the functional study, the patient's medication should usually be continued.
