A New Detection Method of ECG Based on Wavelet Transform

QIU Ya-zhu,FENG Jun(College of Mathematics and Software Science, Sichuan Normal University, Chengdu 610066, Sichuan)  
In this paper, a preprocessing technique on ECG data is performed with orthonormal wavelet packets. Wavelet decomposition of signal of the preprocessed signal was obtained by using Mallat's pyramidal algorithm. Then we deal with the detail signal of 2~3 scale, the extremes corresponding with R wave have considerably increased, the QRS complex detection rate has improved. The result of QRS detection rate examined by the MIT-BIT arrhythmia database is satisfactory.
