摘要
为了解决心电图QRS波检测的问题,研究了一种基于自适应小波变换来检测QRS波的算法。该方法用心电信号的小波变换作为自适应白化滤波器的输入,然后对白化滤波后的输出进行匹配滤波和阈值检测来识别出QRS波。采用该方法,有利于减小检测的误检率以及提高运行速度。
An electrocardiogram QRS complex detection mathed is developed based on selfadaptation algorithm and wavelet transform. This algorithm takes the wavelet transform of the EGG signal as the input of the whitened filter and then determines the QRS complex by matching filtering and threshold detecting. Utilizing this method, the rate of the detecting error can be reduced and the calculating speed can be improved.
