A New Multichannel Parallel Network Framework for the Special Structure of Multilead ECG

Algorithm 2

R-peak detection algorithm based on wavelet coefficients.

	Symbol:
	SR: sampling rate
	: original ECG signal, i is the index value
	: detail coefficient of wavelet decomposition in j-layer
	: R-peak detection sequence
	: amplitude threshold
	Process:
	A. Discrete wavelet decomposition of ECG signals and construction of the R-peak detection sequences
	1 5-layer wavelet decomposition of based on Haar wavelet to get d4, d5
	2 calculation of the R-peak detection sequence
	B. Positioning the R-peak position
	1 determination of amplitude threshold
	2 if , the corresponding position of index value i is R-peak position
	3 two adjacent index values i, i^’. if , that is, the interval time is less than 100 ms, then i and indicate the same R-peak. Otherwise, it is a different R-peak.
