EXERCISE electrocardiography has wide application in the diagnosis and treatment of heart disease. This brief review emphasizes its usefulness in the management of patients with suspected or proved coronary heart disease. The following are indications for exercise electrocardiography:
To aid in establishing the presence or absence of "preclinical" coronary heart disease in apparently normal individuals.
To aid in establishing the presence of suspected coronary heart disease.
To assess the functional significance of coronary heart disease: selection of therapy (a) in stable angina pectoris, (b) following myocardial infarction, and (c) following coronary artery bypass surgery.
Evaluation of the risk of sudden cardiac death.
Preclinical Coronary Heart Disease
Exercise electrocardiography is useful in suggesting the presence of coronary heart disease in apparently normal individuals. This information is independent of that provided by measurement of "coronary risk factors" and, moreover, is more specific for coronary heart disease in an
