A system for continuous recording and real-time processing of eight-channel exercise ECGs is presented with emphasis on the algorithms performing the principal signal processing. The hardware and the operational procedures are briefly described. New methods have been developed for the detection, alignment, and selection of complexes to be used in the creation of eight-dimensional average ECG complexes every 10 s. These algorithms are based on digital filter functions approximating low-order Legendre polynomials in order to be robust in the presence of noise.
本文介绍了一种用于连续记录和实时处理八通道运动心电图的系统，重点在于执行主要信号处理的算法。简要描述了硬件和操作程序。已经开发出了新的方法，用于检测、对齐和选择用于每10秒创建八维平均心电图复合体的复合体。这些算法基于近似低阶勒让德多项式的数字滤波器函数，以便在存在噪声的情况下具有鲁棒性。
