Entropy measure of fuzziness in detection of QRS complex in noisy ECG signal

The paper deals with the application of entropy measures of fuzziness to building a detection function of ECG signals. After formulation of the problem the notion of entropy measure of fuzziness is recalled. Next the idea of a fuzzy signal created from the original signal is proposed. Afterwards entropy measures of fuzziness determined for each sample are calculated. The application of this measure to building a detection function of ECG signals is presented. The theoretical considerations are illustrated with digital processing of the real ECG signal.
