Prehospital transmission of the electrocardiogram (ECG) in ST-elevation myocardial infarction patients has been shown to reduce door to treatment time and improve outcome. Acquisition of the ECG tracing is a paramedic skill, thus limiting the benefit of early ECG transmission to primarily urban areas. The purpose of this investigation was to determine whether prehospital ECGs could be transmitted by nonparamedic personnel.
A prospective case series of consecutive patients with a chief complaint of chest pain was conducted. An ECG was transmitted on all eligible patients. Proper lead placement was verified, and the diagnostic quality of the ECG was assessed on emergency department arrival. Time on scene was recorded and compared with historical controls.
Ninety patients were enrolled in the study. An ECG was transmitted successfully in 89 (98.9%) of 90 patients. Accurate lead placement was noted in 89 (98.9%) of 90, and the ECG was of "diagnostic quality" in 85 (95.5%) of 89 patients. There was no increase in scene time during the study period.
Prehospital transmission of diagnostic-quality ECG can be reliably performed by nonparamedic providers.
院前 ST 段抬高型心肌梗死患者心电图（ECG）的传输已被证明可以缩短治疗时间并改善预后。ECG 描记是护理人员的一项技能，因此，早期 ECG 传输的益处主要局限于城市地区。本研究旨在确定非护理人员是否可以传输院前 ECG。
对连续出现胸痛主诉的患者进行前瞻性病例系列研究。对所有符合条件的患者均进行 ECG 传输。到达急诊科时，验证导联放置是否正确，并评估 ECG 的诊断质量。记录现场时间，并与历史对照进行比较。
本研究共纳入 90 例患者。在 90 例患者中，成功传输了 89 例（98.9%）ECG。在 90 例患者中，有 89 例（98.9%）导联位置准确，89 例（95.5%）ECG 为“诊断质量”。在研究期间，现场时间没有增加。
非护理人员可以可靠地传输诊断质量的院前 ECG。
