    AbstractThe objective of this study was to prospectively determine the utility, efficiency, and reliability of early prehospital 12-lead electrocardiogram (ECG) application, the improvement in prehospital diagnostic accuracy, and paramedic and base physician opinions regarding early application of prehospital 12-lead ECGs in a broad range of stable chest pain patients. The patient population consisted of cooperative, stable adult prehospital patients with a chief complaint of nontraumatic chest pain of presumed ischemic origin. From July 17, 1989 through January 1, 1990 paramedics acquired prehospital 12-lead ECGs on 680 stable adult chest pain patients. Factors affecting prehospital 12-lead ECG application were evaluated. Paramedic application of prehospital 12-lead ECGs was found to be efficient and reliable, and it can be applied to most cooperative stable adult prehospital chest pain patients. Prehospital 12-lead ECGs significantly improve base physicians' diagnostic accuracy in myocardial infarction, angina, and nonischemic chest pain patients. Paramedic and base physicians' opinions regarding early application of prehospital 12-lead ECGs during patient evaluation were favorable.
