Abstract :
The capabilities of a nonlinear signal decomposition method based on nested median filters for electrocardiogram (ECG) analysis are demonstrated. This method is comparable to linear scale-space filtering in terms of computation cost but outperforms it with regard to detection accuracy of characteristic points of ECGs (e.g. the T-wave offset). Obtained results are validated on the CSE database of ECGs
