心电信号检测中滤除肌电干扰的方法

心电信号检测是医生诊断治疗心血管疾病的重要辅助手段,但由于心电信号检测实际条件不理想,心电信号中常混有各种干扰信号,常见有肌电干扰、基线漂移和工频干扰。文中针对肌电干扰,采用数字滤波方法进行了去除噪声的滤波器设计。并通过对心电图信号滤波器的设计,不仅提高了ECG信号滤波器的去噪效果,且提高了工作效率。

EMG Interference Filtering in ECG Detection

ECG signal detection is an important auxiliary means of doctor diagnosis treatment of cardiovascular disease, but due to the fact that ECG signal detection actual conditions are not ideal, ECG signal is often mixed with various kinds of interference signals, among which are EMG noise, the baseline drift and power-line interference. In this paper, the digital filtering method is used to eliminate the noises in ECG signals. The design of ECG signal filter improves both denoising effect and efficiency.
