A P-Wave Detection Method Based on Wavelet Transform and Waveform Information

XIA Hengchao,ZHAN Yongqi, CHENG Xuhua. 1 Mechatronics Research Institute,Shanghai Jiaotong University,Shanghai\ 200030;2 Agricultural Machine Institute, Huaining Anhui 246100  
ECG signal is decomposed by wavelet transform first.Then all P wave peaks are located based on modulus maximum values.After determining,P onset points and P offset points,of each P wave are located by a simple and efficient algorithm,we get radians of P waves and correlation coefficient between P waves and line P waves,which we used to select out the true P waves.We used this method to detect the P wave of nine thirty minute long files from MIT/BIH ECG database,and got satisfactory results.
