【Abstract】 Objective To find a new method for detecting the characteristic point in ECG. Method Binomial wavelet was designed and used to make wavelet transformation of real ECG signal to detect the characteristic points. Result The method of detection with binomial wavelet transformation was proved to be accurate and reliable. Conclusion Detection of characterized points with symmetric binomial wavelet transformation is simple and needs no pretreatment. It is useful in clinical at practice and research.更多还原
