摘要
本文介绍一种心电图（ＥＣＧ）滤波方法。该方法以‘最小二乘法’为准则，用三次Ｂ－样条函数构成拟合函数，相应地滤除ＥＣＧ信号中的基线漂移、５０Ｈｚ工频干扰和肌电干扰。实验结果表明：该方法不失为一种ＥＣＧ滤波方法。
A filtering method for ECG is introdued with the purpose of filtering out the baseline drift,50Hz Powerline and electromyographic interference in ECG signals. The' least square method' was used as criteria The cubic B-spline function was used to form a quasi-function.Experimental results proved that it is an efficient filtering method.
