A filter bank-based algorithm improved the signal-to-noise ratio for Gaussian and muscle noise in stress-type ECGs compared to mean and median averaging methods.
Does a Filter Bank-based algorithm improve the signal-to-noise ratio in stress ECGs compared to Mean and Median averaging methods?
A Filter Bank-based algorithm effectively removes noise from stress ECGs, improving the signal-to-noise ratio better than traditional averaging methods.
The algorithm presented is based on subband processing of the electrocardiogram (EGG), using Filter Banks (FB), and removes noise from stress-type ECGs. For Gaussian noise the FB-based method improves the signal-to-noise ratio (SNR), significantly better than the Mean and Median averaging methods. For muscle noise the FB-based method improves the SNR comparatively better than the Mean and Median averaging methods. The FB-based algorithm offers a way to process specific time periods in the heart beat cycle and remove noise in specific frequency bands.
Afonso et al. (Tue,) conducted a other in Stress-type ECG noise. Filter bank-based processing algorithm vs. Mean and Median averaging methods was evaluated on Signal-to-noise ratio (SNR).
