Using Biorthogonal Wavelet Filter Bank for ECG Detection and Reconstruction

Based on perfect reconstruction conditions for dual\|channel filter bank,we designed a biorthogonal filter bank based on quadratic spline wavelet.It was implemented that ECG signal was decomposed and completely reconstructed,with noise depressed.Furthermore,it was also used to detect R wave,and good results were obtained.By using this method,correct detection rate of QRS complexes could be up to 99\^62%,which was verified by MIT/BIH ECG signal database.
