In this paper, an electrocardiogram signal-processing scheme is proposed. The proposed algorithm involves morphological processing of a sampled ECG signal using Daubechies’ wavelet transform. The wavelet filter with scaling function conforms more closely to the shape of the ECG signal. QRS complexes are detected, and each complex is used to locate the peaks of the individual waves. By using this method, the detection rate of QRS complexes is close to 99.77% for the MIT/BIH arrhythmia database. The results show that the proposed method is effective, simple, suitable and accurate for practical application.
