TLDR
In this paper, a solution to this problem is proposed by applying approximation filtering with dynamically varied number of samples and weighting coefficients, depending on the ECG signal slope, where the slope measure used is the absolute value of the product of the tilts of two adjacent 10 ms segments sliding along the signal.About:

A Nonlinear Bayesian Filtering Framework for ECG Denoising
TL;DR: A nonlinear Bayesian filtering framework is proposed for the filtering of single channel noisy electrocardiogram (ECG) recordings, demonstrating superior results compared with conventional ECG denoising approaches such as bandpass filtering, adaptive filtering, and waveletDenoising, over a wide range of ECG SNRs.

TL;DR: To prevent the ill-conditioning matrix in the RLS algorithm when the noise is very small, white noise to the auxiliary input is added and the experiment shows that this approach can significantly improve the condition of the matrix.
