R- AN APPARATUS FOR DETECTING R-PEAK IN ELECTROCARDIOGRAM SIGNAL BY USING WAVELET TRANSFORM AND MODIFIED SHANNON ENERGY ENVELOPE AND THE METHOD THEREOF

摘要

The present invention relates to an apparatus for detecting an R-peak in an electrocardiogram signal using wavelet transform and a modified shannon energy envelope and a method thereof. The apparatus and method robust to noise enable high accurate and fast operation processing by performing down-sampling on an electrocardiogram signal through wavelet transform, applying soft crystals for noise reduction to efficiently perform noise reduction, and performing a process so that an R-peak may be extracted from a modified Shannon energy envelope and peak energy envelope having a signal differentiation process and magnitude normalization process.
