Adaptive recurrent system for noise cancellation and arrhythmia detection

Original language description

A new LMS-based adaptive filter for preprocessing and analysis of ECG signals recorded under conditions of stress-tests is introduced. The adaptive filter was developed to cancel motion artifacts and myopotentials and to detect diagnostically significantwaves in the ECG signal, e.g. arrhythmias. The new filter exploits a repetitivity of the ECG signal for optimal removing of the nonstationary noise. It uses a vector-variable-step-size LMS algorithm to adjust filter weights according to the nonstationarry properties of the processed signal. The developed system was tested on real signals and on the CSE signal library, and the results are described.
