摘要

Signal averaging is a general and effective method to reduce noise in ECG late potentials detection, but it may also extinguish the beat to beat variance. Other filters applied to the time sequence may destroy the late potentials when trying to filter out the noise. Filters, which are beat sequence originated, are proposed here to preserve beat to beat variance as well as late potentials as much as possible. A few different methods, including low pass and Wiener adaptive beat sequenced filters are applied and discussed.
