An impulse rejection filter algorithm based on moving window was proposed and applied to artifact removal in R-R interval series.Firstly,the R-R interval series was broken to several segments based on a moving window of a specified width.Secondly,the corresponding impulse rejection filter was computed for each segment of the R-R interval series.Subsequently,the filter was enhanced by a signal enhancement algorithm,which made the artifacts distinguished easily from the normal points.Finally,accor...
