Abstract:
Objective To research the precise location algorithm of onset and end of one wave for QRS in ECG. Methods During monitoring the ambulatory electrocardiograph (AECG),it was necessary to design new automatic analysis algorithms. The windows formed by filtering and integrating process could be considered as the fiducially mark. From the window,the apex of Q wave and S wave could be recognized. Results Introducing an auxiliary line from the apex,we could judge the boundary of the Q and S wave with the distance from ECG curve to the line. Conclusion Many cases studies inelicate that the algorithm is of low level locating error,about one sample point,and the accuracy of judgement of S wave boundary is raised obviously compared with the same kind of software in the world.
