Discrete Wavelet Transform based algorithm for recognition of QRS complexes

This paper proposes the application of Discrete Wavelet Transform (DWT) to detect the QRS of an electrocardiogram (ECG) signal. Wavelet Transform provides efficient localization in both time and frequency. In preprocessing stage, DWT is used to remove the baseline wander in the ECG signal. The performance of the algorithm of QRS detection is evaluated… CONTINUE READING
