　　目的：探讨常规静息心电图ST-T改变在老年冠心病诊断中的应用效果，以供参考。方法：选择2010年2月-2013年1月接受冠脉造影的135例疑诊冠心病老年患者作为研究对象，均进行常规静息心电图检查。以冠脉造影结果阳性为冠心病确诊依据，比较心电图检查结果与冠脉造影结果的差异性。结果：冠脉造影结果阳性68例，占50.37%，分析常规静息心电图ST-T改变情况，心电图阳性84例，阳性率为62.22%；其中真阳性38例，假阳性46例。心电图阴性51例，阴性率为37.78%；其中假阴性30例，真阴性21例。心电图诊断正确率为43.71%。结论：常规静息心电图ST-T改变对老年冠心病的诊断价值不高，临床不应将其作为确诊老年冠心病的依据，仅可作为辅助诊断手段。

Objective:Investigate the application of normal resting ECG ST-T changes in the diagnosis of aged coronary heart disease,for reference. Methods:Select 135 cases from Feb 2010 to Jan 2013 as research object,were routine ECG examination. Results of coronary arteriography for coronary heart disease diagnosis basis,compare the differences between ECG and coronary angiography.Results:The results of coronary arteriography in 68 cases,accounting for 50.37%.conventional resting ECG ST-T changes of ECG,84 cases were positive,accounting for 62.22%;of which 38 cases true positive,46 cases false positive. ECG of 51 cases were negative,accounting for 37.78%;of which 30 cases false negative,21 cases true negative.The correct rate of ECG diagnosis was 43.71%.Conclusion:Routine resting ECG ST-T change the value in the diagnosis of coronary heart disease is not high,clinical should not be used as diagnosis of senile coronary heart disease according to,can only be used as auxiliary diagnostic means.
