目的探讨高龄冠心病患者常规静息心电图ST-T改变的诊断精确度。方法随机选取2012年6月至2014年6月高龄冠心病患者128例,均采用常规静息心电图和冠状动脉造影检查,比较分析其检测结果。结果常规静息心电图冠心病确诊率为48.44%,冠状动脉造影确诊率为89.06%,二者比较差异有统计学意义(P<0.05)。结论常规静息心电图ST-T改变对老年冠心病患者的诊断精确度不高,可作为临床辅助诊断。
Objective To investigate the diagnostic accuracy of routine resting electrocardiogram ST-T in elderly patients with coronary heart disease. Methods A total of 128 elderly patients with coronary heart disease were randomly selected from June 2012 to June 2014. All patients were examined by routine resting electrocardiogram and coronary angiography. The results were compared and analyzed. Results The diagnosis rate of routine resting electrocardiographic coronary heart disease was 48.44% and the rate of coronary angiography was 89.06%. There was significant difference between the two (P <0.05). Conclusion The diagnostic accuracy of routine resting ECG ST-T changes in elderly patients with coronary heart disease is not high, and can be used as a clinical diagnosis.
