title: Detection Of QRS-Wave In Electrocardiogram: Based On Kalman And Wavelets.
abstract: An algorithm using wavelets and Kalman filtering method has been developed for QRS detection. The algorithm takes following steps: i) We use a RLS adaptive algorithm to establish a model of the electrocardiogram. Thus the algorithm can change its own model according to the change of the electrocardiogram. ii) Based on the model established in stage i), we combined the wavelet and Kalman Algorithm, decomposed the signal to several scales, filtering the signal in each scale. And then, iii)A decision rule is used to determine the QRS complex. The method was tested on ECG data form the MIT database, and experimental results show that the method is effective, and the influence of the noise can be eliminated.
