Abstract :
An adaptive filtering system for the assessment of a dynamically changing exercise ECG signal is described. The system is composed of two time-sequenced recurrent filters working in parallel. At the output the differential signal component related to the exercise with improved signal to noise ratio is obtained. The system showed its clinical usefulness in the assessment of the patients with hypertrophic cardiomyopathy and revealed its superiority compared with the signal averaging process used as standard
