The use of computers in the exercise of electrocardiography is considered. The problems related to this use concern the choice of leads, the filtration of the signal, the recognition of characteristic segments of ECG, the calculation of various indexes and their statistical evaluation for diagnostic purposes. The authors use a bipolar derivation filtered by averaging and digital filters. The characteristic points of ECG are recognized by the analysis of the curvature. The Tchebycheff coefficients of the S-T tract are evaluated; they appeared to be a very good means for judging positive and negative cases.
本文考虑了计算机在心电图检查中的应用。与这种应用相关的问题涉及导联的选择、信号滤波、心电图特征段的识别、各种指标的计算及其用于诊断目的的统计评估。作者使用了通过平均滤波和数字滤波的双极导联。通过曲率分析来识别心电图的特征点。评估了S-T段的切比雪夫系数；它们似乎是判断阳性和阴性病例的非常好的方法。
