Potentials recorded from the heart by the FRANK lead system are expressed in figures by means of analog-to-digital convertors. An elementary table is thus obtained, in which positive and negative numbers of X, Y, Z of eight possible combinations are called octants and have been numbered successively. The sequence of octants during a single depolarization is individual, but characteristic for a given group. Patients after myocardial infarction were examined and classified in this manner. Further more, peak amplitudes were assessed as the second parameter, i.e. the maxima of positive and negative potentials of X, Y, Z. The octants and peaks produce a network of a higher order to that in examined patients and may serve for the diagnostics of heart infarction. The method is intended for qualitative evaluation of coronary insufficiency, for which it provides novel information. It introduces computer techniques into electrocardiography.
通过FRANK导联系统从心脏记录的电位由模数转换器以数字形式表示。由此得到一个基本表，其中X、Y、Z的正负数字的八种可能组合被称为卦限，并已连续编号。单次去极化期间卦限的顺序是个体性的，但对于给定群体具有特征性。对心肌梗死后的患者进行了检查并以此方式进行分类。此外，将峰值幅度作为第二个参数进行评估，即X、Y、Z的正电位和负电位的最大值。卦限和峰值产生了一个比所检查患者中更高阶的网络，可用于心脏梗死的诊断。该方法旨在对冠状动脉供血不足进行定性评估，为此它提供了新的信息。它将计算机技术引入了心电图学。
