【摘要】目的探讨12导动态心电图与常规心电图STT 的差别,为12导动态心电图(AECG)STT的诊断标准提供依据。方法检测对象共600人用常规心电图(RECG)的连接方式和12导动态心电图的连接方式分别描记心电图,然后比较两种连接方式心电图STT的差别。结果两种导联联接方式,ST段正常或改变基本一致的555例,%,但AECG的ST改变较RECG显著;T波正常或改变基本一致的561例,%;QTc 间期:两种连接方式均在正常范围内586例,%。结论(1)两种联接方式,%, 但AECG的ST改变较RECG显著,所以AECG的ST诊断标准应比RECG的ST诊断标准更为严格;(2)%差别较ST段小,在分析12导联AECG T波时,可适当考虑这一情况;(3)两种联接方式QTc %,可考虑使用同一诊断标准。

ABSTRACT Objective To study the difference of ST
T parameters between 12-lead dynamic electrocardiogram and routine electrocardiogrm so as to provide proofs for the diagnozing standard for 12-lead dynamic Both 12-lead dynamic electrocardiogram and routine electrocardiogram were applied to 600 patients, and the difference of STT of both electrocardiograms 555 cases shared samilarity in normal ST or changed ST in both electrocardiograms with the consistent rate of %, but the change of ST in 12-lead dynamic electrocardiogram was more significant than that in routine electrocardiogrm; 561 cases shared similarity in the normal T-wave or changed T-wave with the consistent rate of %; 586 cases showed normal QTc intervals in both electrocardiograms with consistent rate of %.Conclusion (1) As the change of ST in 1
