One of the methods of recording late ventricular potentials, markers of decelerated depolarization of the heart ventricles, is depicted. The complex suggested by the authors consists of an interface connected to the personal computer, a block for cardiosignal processing, and an analog-to-digital converter. The averaging is realized after preliminary signal processing, which results in the computation of the mean period of the QRS. The mode of automatic amplification is provided as are alterations of the lower frequency of the section of the band-pass filters as well as the switching on of the rejection filter.
描述了一种记录晚期心室电位的方法，晚期心室电位是心室去极化减速的标志。作者提出的系统由连接到个人计算机的接口、心脏信号处理模块和模数转换器组成。在对信号进行预处理后进行平均化处理，从而计算出QRS波群的平均周期。系统提供自动放大模式、带通滤波器低频段的改变以及抑制滤波器的开启。
