目的评价远程实时传输12导联心电图对ST段抬高性急性心肌梗死(STEMI)的诊断价值.方法选择40例STEMI患者采用同时进行远程实时传输12导联心电图和常规12导联心电图记录,采用配对t检验和秩和检验比较相同导联各波形的时限、振幅及ST段偏移程度,用Pearson分析ST段抬高相关性.结果两种方法所测得STEMI患者的心电图各波形的时限、振幅及ST段偏移程度等参数间差异无统计学意义(P＞0.05),两种方法检测的ST抬高幅度高度相关(r =0.912,P=0.000),二者之间的符合率高(Kappa值为0.976),结论远程实时传输12导联心电图监测系统所记录和传输的心电信号准确、可靠,可用于STEMI的院前诊断.

Objective To evaluate the pre-hospital diagnostic reliability of real-time tele-transmission of 12-lead electrocardiogram of patients with ST-segment elevated acute myocardial infarction (STEMI).Methods The 12-lead electrocardiogram was simultaneously recorded with real-time tele-transmission system and a conventional electrocardiograph in 40 STEMI cases.The width and amplitude of each wave,the deviated amplitude of ST-segment in the same leads were compared by t-test and rank-sum test.Results There were no statistical differences in the width and amplitude of P wave,QRS wave and t wave as well as the deviated altitude of ST-segment between the two separate electrocardiographs (P ＞0.05).There was a significant positive correlation between the two ECG devices in respect of ST-segment elevated altitude (r =0.912,P =0.000).The differential ability of ST-segment elevation between two separate ECG devices kept highly consistent (Kappa value:0.976).Conclusions Real-time tele-transmission of 12-lead electrocardiogram is reliable for the pre-hospital diagnosis of STEMI.
