You also want a high-pass filter with a cut-off of about 5 Hz to get rid of baseline drift etc. Further to that, you should probably be using filtfilt so there is no phase distortion - after all, in this case you ... WebThis method could effectively distinguish R-peaks from high amplitude noises but failed to detect R-peaks when abrupt jump of baseline appeared. Some researchers also conducted ECG feature extraction without predenoising [ 22, 23 ]. The detection accuracy could reach up to 94.8%, although much lower than that acquired from the denoised signals. philosophe marie robert
