摘要
以确定的Q波峰点、R波峰点和S波峰点为基准,避开了在全部ECG时域内检测搜索的方式,通过基于LabVIEW相关功能VI检测Q-R段及R-S段间波峰点/波谷点的有无及相应的时限长短,分析了QRS波切迹、扭挫和顿结的检测方法;实验结果表明,在具备R峰点确定位置的基础上,这一检测高频心电信号(HFECG)的方法具有算法简化,高频成份检出率高的特点。该方法充分运用了虚拟仪器的最新信号处理技术,可在HFECG的计算机自动分析领域提供参考。
By the given exactly information of Q-peak, R-peak and S-peak, a HFECG detecting method of Notching. Slurring and Beading on QRS wave was analyses in paper, the method avoid all the time domain analyses of ECG, in which the result shows that it makes signal processing faster and the algorithm simpler, and get a high HFECG extracting rate. The method used a latest technology of Virtual Instrument on signal processing, which can offer reference to the domain of HFECG auto-analysis.
