Key result
Filtering ECG signals using a combination of Empirical Mode Decomposition (EMD) or Ensemble EMD (EEMD) with an adaptive RLS filter improves noise and artifact removal compared to other methods.
The combination of EMD or EEMD with an adaptive RLS filter provides an effective method for ECG denoising, though it may attenuate R-peak amplitudes.
May aid ECG quality in noisy settings; extends denoising methods but leaves open clinical validation.

My Hachem El yousfiAlaou (2020) studied ECG noise and artifacts (n=90). EMD and EEMD combined with adaptive RLS filter vs. EMD or EEMD alone was evaluated on Mean Square Error (MSE) of filtered signals. Filtering ECG signals using a combination of Empirical Mode Decomposition (EMD) or Ensemble EMD (EEMD) with an adaptive RLS filter improves noise and artifact removal compared to other methods.
