451 male patients with typical or atypical angina pectoris syndrome were examined and on account of the degree of severity of the coronary stenosis are subdivided into four groups. With the help of the discriminance analysis of a hybrid ECG (conventional and body surface ECG after Frank) the patients were coordinated to these four groups, in order to test its clinical valency for the recognition of the coronary heart disease. It was stated that in a scalar interpretation of the body surface ECG in every case the conventional leads V3 and/or II after Einthoven must additionally be registered and evaluated. In a scalar and vectorial interpretation of the body surface ECG a significant gain of information was possible only by taking into consideration a great number of scalar parameters of the conventional ECG. The result of the discriminance analysis with the optimum quantity (p = 88) of scalar and vectorial parameters of the two derivation systems contained a correct classification rate of 84.1%, in which case 88.6% of the post-infarction ECG were classified correctly. Neither by means of the conventional nor by means of the body surface ECG after Frank an equivalent result could be yielded. When a computer technology is existing (automatic statement of measuring values with following discriminance analysis) therefore in specialized clinics such a hybrid ECG should be used.
对451例典型或非典型心绞痛综合征男性患者进行了检查，并根据冠状动脉狭窄的严重程度分为四组。借助混合心电图（常规心电图和Frank导联后的体表心电图）的判别分析，将患者归入这四组，以测试其对冠心病识别的临床价值。结果表明，在对体表心电图进行标量解释时，每种情况下都必须额外记录和评估Einthoven常规导联V3和/或II导联。在对体表心电图进行标量和矢量解释时，只有考虑常规心电图的大量标量参数，才可能显著增加信息量。对两个导联系统的标量和矢量参数的最佳数量（p = 88）进行判别分析的结果显示，正确分类率为84.1%，其中88.6%的心肌梗死后心电图被正确分类。无论是通过常规心电图还是Frank导联后的体表心电图，都无法得出等效结果。因此，在有计算机技术（自动记录测量值并随后进行判别分析）的情况下，在专科医院应使用这种混合心电图。
