A system for noncontact ECG recording is proposed that measures the real time electrode-body capacitance concurrently with the ECG as a reference signal for motion artifact reduction. Simultaneous recordings of these two signals from the human body in the presence of electrode motion artifacts are shown and an adaptive least-mean-squares (LMS) filtering algorithm run on these signals is demonstrated to be able to reduce the severity of certain types of electrode motion artifacts.
本文提出了一种非接触式心电图记录系统,该系统在记录心电图的同时测量实时电极-人体电容,以此作为减少运动伪影的参考信号。文中展示了在存在电极运动伪影的情况下从人体同步记录这两种信号的情况,并证明在这些信号上运行的自适应最小均方(LMS)滤波算法能够降低某些类型电极运动伪影的严重程度。
