摘　　要：心电运动试验是诊断冠心病及心脏功能评估的重要方法,然常规运动试验有局限性.我们为探讨最大ST段/心率斜率(斜率)与心肌缺血的确切关系及意义,从实用角度出发,对斜率测试方法进行改良,对其诊断作了研究.对22例患者作下列两项检查:平板运动试验并测试最大ST段/心率斜率和2周内行静息与运动心肌灌注SPECT.结果发现:斜率在检测冠心病程度上准确度高于ST段压低及其它常规分级运动试验指标.Exercise eleetrocardiography testing has been accepted as an important means of assessment of myocardial ischemia and cardiac function, but routine exercise testing has its limitations and drawbacks. A new index:the maximal ST segment/heart rate slope was proposed as an excellent predictor of both the presence and severity of CAD. Our study was undertaken on the index in the circles of diagncsis with the method of obtaining the slope medified based on clinical applicability. 22 patients were examined in following way: (1). Treadmill exercise test and calculation of maximal ST/HR slope.(2).Rest and exercise Tc-99m myocardial perfusion imaging using SPECT. The results showed that the maximal ST/HR slope, used as and index of myocardial ischemia, more reliably predicted the presense and severity of CAD than ST segment depression and other indices derived from routine exercise testing.
