摘要

The present invention relates to an apparatus for enhancing signals In ECGs including artefacts, said apparatus comprising a mean value unit (4) for evaluating from an ECG signal the curve shape of a predetermined number of beats from the beginning of a QRS complex to the end of a T wave and forming therefrom a mean value beat. A subtracting unit (3) subtracts the mean value beat from the ECG signal of an actual beat to thereby obtain a residual signal. A FIR filter unit (4) subjects the residual signal to high-low-pass filtering and delays it to provide a filtered signal to which the mean value beat is added in an adding unit.
