摘　　要：提出了一种基于小波变换与形态学运算的R波检测算法。采用二进Marr小波的Mallat算法对心电信号作多分辨率分解,利用数学形态学运算突出信号的峰谷点特征,将小波变换模极大值检测原理与形态学峰谷检测算法相结合,不仅可以实现对R波的准确检测和精确定位,同时也具有较好的算法实时性。A new algorithm for detecting R-wave of ECG was proposed on the basis of wavelet transform and morphological operation. In this paper, MaUat algorithm based on dyadic Marr wavelet transforms was used to multi-resolution analysis on the signal, and mathematical morphology operation was used to clarify tbe signal＇s peaks and valleys. Test results showed that the detection method not only can detect accurately and localize precisely to the R-wave of EGG signal, but also can achieve the real-time detection.
