| 摘 要： | 在心电信号的QRS波群检测算法中,最为有效的是把待测信号在时域或频域内进行适当的变换,以分离或加强QRS分量,抑制各种噪声干扰,再进行判决定位。简要回顾了以滤波器为代表的单一尺度时频变换方法、以小波分析为代表的多尺度时频变换方法,以及另一种较新的多尺度时频变换分析方法—经验模式分解(EMD)等在QRS波群检测中的应用情况和发展前景。

| Abstract: | In detecting algorithm of QRS complex in ECG,it is the most effective to separate or reinforce the QRS complex and restrain noise before judgment and location by transform the ECG in time or frequency scale. In this paper, the development and trend of those detecting algorithm on time-frequency transform are reviewed from single scale detecting ways, such as filters to multi-scales detecting ways based on wavelet analysis and a new multi-scales method experimental mode decomposition(EMD). |
