摘　　要：目的:探讨健康人12导联常规心电图(RLECG)与S_5同步记录12导联心电图(S_5ECG)之间的差异,以便更好的做出诊断。方法:50例健康体检者,分别由同一技术人员在5 min内完成RLECG及S_5ECG的描记记录。结果:两种导联系统ST-T比较:avF、V_1导联的J点(以J_(avF、V1)表示,以后类推)及ST_(Ⅲ、avF、V1、V4、V5)的下移程度,T_(Ⅰ、Ⅱ、avR、avL、V2)的振幅改变,差异有统计学意义(P<0.05)。Q波时间、Q/R振幅比值比较:Q_(avR、V1、V4-6)的时间变化,Q/R_(Ⅲ、avR、avF、V4-6)比值的大小,差异有统计学意义(P<0.05)。结论:健康人的心电图在两种导联系统的ST-T、QRS波群存在差异,S_5ECG的下壁与侧壁心肌缺血的假性改变高于RLECG,不宜用于人群的筛查。Objective：To explore the difference between the 12 lead electrocardiogram（RLECG）and the 12 lead electrocardiogram（S5ECG）synchronously with S5 in order to make a better diagnosis.Methods：A total of 50 healthy people were enrolled in the study.RLECG and S5ECG records were recorded by the same technician in 5 min.Results：Compared with ST-T waves between the two systems：the variation of the decline of the JavF、v1and STⅢ、avF、V1、V4、V5and the amplitude of the TⅠ、Ⅱ、avR、avL、V2are statistically significant（P〈0.05）.Also,compared with the Q wave,Q/R ratio：the changes in the time of the QavR、V1、V4-6and the size of the ratio of the Q/RⅢ、avR、avF、V4-6are statistically significant（P〈0.05）.Conclusion：There are differences in the ST-T and QRS waves in the two lead systems of the healthy people.The false change of the inferior and lateral wall myocardial ischemia of S5ECG is higher than that of RLECG,and it is not suitable for the screening of the population.
