A FAST ALGORITHM FOR POWER-LINE INTERFERENCE ELIMINATION FROM ECG SIGNAL

为消除动态心电记录中工频干扰的影响,本文给出一种新颖简洁的基于噪声提取的工频干扰抑制算法。结果表明,该算法能快速跟踪干扰频率和幅度的变化,可靠地抑制住工频干扰,滤波输出失真小,可以满足临床分析的要求。

To eliminate power-line interference in dynamic ECG recording, we present a simple effective power-line interference elimination algorithm based on noise extracting. Results show that this method can track the frequency and amplitude variations of interference quickly and eliminate interference reliably, the output of filtering has little distortion and can satisfy the requirement of clinical analysis.
