摘要
本文是基于小波变换的心电信号的QRS波检测的应用研究 .利用二进样条小波对心电信号按Mallat算法进行分解滤波 ,消除干扰 ,再利用小波变换与信号奇异点之间的关系 ,在2 3尺度下对QRS波进行检测 .为更有效地提高QRS波的检测率 。
The paper deals with the research on the application of QRS wave detection based on wavelet transformation signals. Signals are filtered by Mallet Algorithm using the dyadic spline wavelets, and disturbances are cancelled. Use the relation between WT and signal break points to detect QRS waves in 2 3 scale. To get the better rate of QRS waves detection, physiological characteristies of humans are studied for redetection.
