The informative reliability of automated ECG analyzers operating under dynamic conditions is mainly dependent upon the noise immunity of R-wave selectors. The selector is developed that selects sequentially input positive spikes, at first, for the rate of negative slope and, then, for its duration thus providing much greater noise immunity as compared to commonly used models with built-in band-pass or resonant filters. So, the errors of detecting events for one of the test-signals for above selectors are 1,8%, 22% and 17%, respectively.
在动态条件下运行的自动心电图分析仪的信息可靠性主要取决于R波选择器的抗噪声能力。所开发的选择器首先根据负斜率速率、然后根据其持续时间依次选择输入的正尖峰，因此与具有内置带通或谐振滤波器的常用型号相比，具有更高的抗噪声能力。所以，上述选择器对其中一个测试信号的事件检测误差分别为1.8%、22%和17%。
