we propose to mitigate baseline wander either by using a line code or by using active baseline restoration.
我们使用线性编码或者使用在接收器上活性基线恢复来去除基线偏移。
conclusion the baseline wander is accurately removed and the ecg waveform is better retained. , which lays foundation for the following ecg automatic detection.
结论:该方法可以準确地去除基线漂移分量,并保留ecg的波形变化,为后续的ecg自动检测奠定了基础。
baseline wander is one of the important factors that affect the detective of electrocardiograph.
心电图中的低频干扰是影响心电图识别的一个重要因素。
the main idea of this method builds on the principle that the approximation signal of multi-resolution analysis characterizes the baseline wander of ecg almost fully.
该方法的基本思想是:通过对ecg信号进行多尺度分解,利用分解后所得的逼近信号充分逼近ecg中的基线漂移噪声的特性,从而滤除ecg中的基线漂移分量。
