The 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.
本研究的目的是前瞻性地确定早期院前12导联心电图（ECG）应用的效用、效率和可靠性，院前诊断准确性的提高，以及护理人员和基层医生对在广泛的稳定胸痛患者中早期应用院前12导联ECG的看法。患者群体包括主诉为推测为缺血性起源的非创伤性胸痛的合作、稳定的成年院前患者。从1989年7月17日至1990年1月1日，护理人员为680例稳定的成年胸痛患者采集了院前12导联ECG。评估了影响院前12导联ECG应用的因素。发现护理人员应用院前12导联ECG是有效且可靠的，并且它可应用于大多数合作的稳定成年院前胸痛患者。院前12导联ECG显著提高了基层医生对心肌梗死、心绞痛和非缺血性胸痛患者的诊断准确性。护理人员和基层医生对在患者评估期间早期应用院前12导联ECG的看法是积极的。
