Abstract

The adaptive temporal selector increases 2-3 times the noise immunity of detectors of ECG informative elements, especially of R = R-wave detectors, that is of particular importance when patient moves. The selector produces the protective time interval the duration of which is conditioned by the duration of the preceeding R = R-interval, so the probability of false detections caused by noise is reduced. The optimum protective time interval should constitute 84 per cent of the preceeding R = R-interval, the error should not exceed +/- 5%.

摘要

自适应时间选择器可将心电图信息元素检测器(尤其是R波检测器,即R = R波检测器)的抗噪声能力提高2至3倍,这在患者移动时尤为重要。该选择器产生一个保护时间间隔,其持续时间由前一个R = R间隔的持续时间决定,因此可降低由噪声引起的误检测概率。最佳保护时间间隔应为前一个R = R间隔的84%,误差不应超过+/-5%。
