| Abstract: | Using the special time-frequency properties of Marr wavelet function and the direct algorithm of discrete wavelet transforms,the QRS complexes are identified from ECG signal.By using the MIT/BIH(Massachusetts Institute of Technology / Boston's Beth Israel Hospital) arrhythmia database and the applications in clinic,the precise detection method can be used to accurately detect and precisely localize the QRS complex in the ECG signal with the serious noise. |
