【摘要】 对心电信号的滤波算法进行了改进。在利用小波变换实现心电图信号滤波算法的基础上 ,增加了对 2 3尺度下小波分解所得细节信号的模极大值对的检测功能 ,以修复因滤波受损的心电信号的QRS波。经MIT/BIH标准心电数据库验证 ,试验表明 ,该方法行之有效更多还原

【Abstract】 The modified filtering method for ECG by using WT was given.Based on the method of noise cancellation on ECG signal using wavelet transform,a function of checking module maximum value on detail signal of the scale 2 3 was used in order to retrieve the losing QRS complex due to filtering.ECG signals taken from the MIT/BIH database were tested. Our experimental results demonstrate this is an efficient filtering method.更多还原
