目的研究心电多相信息分析诊断技术,从而对心脏缺血性疾病做出早期诊断。方法对492例确诊、疑诊缺血性心脏病及正常人群进行十二导联心电图及心脏负荷试验等项目检查和分析。结果缺血性改变的阳性率S-T段异常组98.34%、运动试验组92.00%、临床疑诊组72.16%、确诊治疗组73.52%、疑诊治疗组16%。对照组4.30%,功能谱阳性率呈阶梯式变化。结论心电图可以观察心肌缺血的程度,还可以通过心电图和运动试验观察治疗效果,指导临床治疗方向。
Objective To study the multi-phase ECG diagnosis and diagnosis technology, and to make early diagnosis of ischemic heart disease. Methods A total of 492 confirmed, suspected ischemic heart disease and normal population were examined and analyzed on 12-lead electrocardiogram and cardiac load test. Results The positive rate of ischemic change was 98.34% in the abnormal S-T segment, 92.00% in the exercise test group, 72.16% in the clinically suspected group, 73.52% in the diagnosed group and 16% in the suspected group. Control group 4.30%, functional spectrum positive rate showed a stepwise change. Conclusion ECG can observe the extent of myocardial ischemia, but also through the ECG and exercise tests to observe the effect of treatment, to guide the direction of clinical treatment.
