A simple synthetic algorithm for ECG noise filtering
In this paper,a simple real-time synthetic algorithm is proposed for the filtering of the noisy electrocardiogram (ECG) recordings.Cardiogram recordings include numerous noncardiac containments.The main noise contains the electromyography (EMG),50HZ power line interference with the harmonic frequencies and baseline wander as well as motion artifacts.To deal with these different kinds of noises,three distinct techniques were used.Firstly,baseline wander was removed by the FIR high-pass filter with Kaiser windows.Then,a simple and narrowband power-line interference notch filter was designed to suppress power-line and harmonic interference.Finally,EMG overlapping with the cardiac components in the frequency domain was suppressed by wavelet denoising.The experimental results demonstrate superior results compared with a single FIR filter and a single wavelet denoising methods.The improved SNR were shown in this paper.This synthetic algorithm is easily implemented by micro-professor in real-time processing and may therefore serves as an effective methods for filtering noisy ECG.
