T hat is the reason w hy the detection method of QRS complexes is w idely researched now adays. By deducing the w avelet transform, it is found that by fast convolution, the phase information can be obtained, by w hich the Rw ave apex can be confirmed accurately . It is another access to detecting zeroamp of w avelet transform in fact, but it is more efficient because it has little reliance on the ampthreshold.
