Adaptive filtration in dynamic ECG signal

859

Abstract

In this paper the adaptive filtration method as applied to the noisy and dynamically changing ECG signal described. At the beginning, the most common types of the adaptive algorithms were discussed and their performance were reviewed. In the final part, the application of the processing system based on two filters connected in parallel was presented and its ability in analysing of the dynamically changing ECG waveforms recorded during exercise test in normal individuals as well as in patients with hypertrophic cardiomyopathy was discussed.

Key words: signal processing, adaptive filtration, high resolution ECG.
