心电图ST-T改变对诊断冠心病价值研究

Evaluation of Diagnosis on Coronary Heart Disease during ST-T Altering and ST Segment Prolonging in ECG

目的心电图检查在冠心病诊断中新价值的探讨。方法观察30例有典型或者不典型心绞痛经冠状动脉造影正常者,并随机抽取同期有同样症状,经冠状动脉造影异常确诊为冠状动脉粥样硬化性心脏病(简称冠心病)者36例进行对比,两组均除外心肌梗塞及电解质紊乱,对其心电图ST-T改变进行对比分析。结果观察组心电图ST-T改变并ST段水平延长为33.3%;对照组ST-T改变并ST段水平延长83.3%。两组对比经济统计学处理有显著性差异(P<0.01)。结论采用心电图ST-T改变并ST段水平延长分析的方法可显著提高冠心病诊断的准确率。

Objective To investigate the new value about diagnosing coronary Heart disease with ECG.Methods Observe 30 normal coronary angiographic patients with typical or untypical anginapectoris,selecting 36 abnormal coronary angiographic patients with the same symptoms at random.The two groups exclude patients with myocardial infarction and electrolytes disorders.To analyze the alternation of ST-T in ECG.Results The observed group has 33.3% alternation of ST-T and ST segment prolonging in ECG.The control group has 83.3% alternation of ST-T and ST-T segment prolonging in ECG.The observed group is significantly lower than the control group（P0.01）.Conclusion The method of analyzing ST-T altering and ST segment prolonging in ECG can significantly improve the accuracy of diagnosing coronary heart disease.
