Study populations were divided into fQRS group and non-fQRS group according to the existence of fQRS on electro- cardiography ( ECG) . Before CRT implantation as well as 6 months after implantation,New York Heart Association ( NYHA) class, ECG and echocardiography were evaluated. Response to ...
ECGKalman algorithmQRS complexWaveletsAn 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 ...

on a standard 12-lead ECG, from the onset of the QRS complex to its terminal components. Indeed, measurement of the QRS duration in a single lead may frequently result in an inaccurate evaluation and, therefore, it should be avoided. The approach to an ECG showing wide QRS complexes ...
QRS wave group detection based on B-Spline wavelet and adaptive threshold An effective algorithm for detecting QRS wave group was presented. The ECG signal is de-composed with the equivalent filter of a biorthogonal spline wavele... Q Chen,J Liu,G Li - International Conference on Computer 被...
In this work, we have developed an electrocardiogram (ECG) feature extraction system based on the multi-resolution wavelet transform. It mainly includes two stages. In the first stage, algorithm is quoted by using discrete wavelet transform for de-noise the signal. In second step multiresolution ...
