对稳定型心绞痛病人和正常人各41例行踏车试验,各项参数用自编程序处理。冠心病最大ST/HR斜率4例正常,37例(90、2%)异常,对照组39例正常,2例(4、9%)异常。稳定型心绞痛者斜率>6.0μv/bpm表示冠脉严重病变者占19.5%。最大ST/HR斜率的敏感性和特异性分别为90.2%和95.1%、均较ST标准为高、对冠心病具有较好的诊断价值。
41 cases of stable angina patients and normal treadmill test, the parameters of the program with self-treatment. The maximum ST / HR slope of coronary heart disease was normal in 4 cases, abnormal in 37 cases (90.2%), normal in control group (39 cases) and abnormal in 2 cases (4,9%). Stable angina pectoris> 6.0μv / bpm said severe coronary lesions accounted for 19.5%. The sensitivity and specificity of the maximum ST / HR slope were 90.2% and 95.1%, respectively, which were higher than the ST standard and had a good diagnostic value for coronary heart disease.
