目的总结心电图ST-T改变对冠心病的诊断价值,为临床诊治工作的开展提供参考依据。方法选择我院2016年收治住院治疗的50例冠心病患者作为实验研究的观察组,选择同期进行健康体检的50人作为实验研究的参照组,对两组实验研究对象临床资料进行回顾性分析。结果:观察组患者心电图ST-T改变阳性率为62%,参照组患者心电图ST-T改变阳性率为32%,组间患者心电图ST-T改变阳性率对比,观察组高于参照组,经统计学计算,P<0.05。结论心电图ST-T改变是冠心病患者主要的体征表现之一,在冠心病诊断方面价值突出,但是心电图ST-T改变涉及到假阴性以及假阳性问题,所以需要早期进行冠脉造影确诊。
Objective To summarize the diagnostic value of ECG ST-T changes in coronary heart disease and provide a reference for the development of clinical diagnosis and treatment. Methods Fifty patients with coronary heart disease admitted to our hospital in 2016 were selected as the experimental group and 50 healthy people were selected as the reference group for the experimental study. The clinical data of the two groups were retrospectively analyzed. Results: The positive rate of ST-T changes in observation group was 62%, while the positive rate of ST-T changes in reference group was 32%. The positive rate of ST-T in ECG was significantly higher in observation group than in reference group. Statistical calculation, P <0.05. Conclusion ECG ST-T changes are one of the main signs in patients with coronary heart disease. It is of great value in the diagnosis of coronary heart disease. However, ST-T ECG changes involve false negatives and false positives. Therefore, coronary angiography is needed for early diagnosis.
