运用心电图、心向量图、超声心动图和收缩时间间期四种无创性检查方法,对100例正常对照者、37例冠心病患者和48例可疑冠心病患者进行了联合次极量卧位蹬车运动试验。结果表明运用联合运动试验的多变数判别分析的方法,将无创性检查与运动相结合,将反映心肌缺血机械变化的指标与ST—T改变的定量化相结合,能有效地克服目前心电图运动试验的假阴性和假阳性,提高冠心病诊断的敏感性、特异性和予测准确性,同时可定量判断冠心病患者的病变程度和心功状态。这是冠心病诊断的一条新途径,需要继续研究。
Four kinds of noninvasive methods of electrocardiogram, echocardiogram, echocardiography and systolic time were applied to 100 patients with normal control, 37 patients with coronary heart disease and 48 patients with suspected coronary heart disease. Motor sports test. The results show that the use of joint exercise test multivariate discriminant analysis method, the combination of noninvasive examination and exercise will be reflected in mechanical changes in myocardial ischemia indicators and ST-T quantitative change combined to effectively overcome the current ECG exercise Test false negative and false positive, improve the diagnosis of coronary heart disease sensitivity, specificity and accuracy of prediction, at the same time quantitatively determine the degree of coronary heart disease patients and cardiac function. This is a new way of diagnosis of coronary heart disease, need to continue to study.
