Since the code of this paper is not open, I implemented the code according this paper with keras framework.

Data preprocess

Data preprocessed in MATLAB. Download data files from https://www.physionet.org/content/qtdb/1.0.0/ with download_QTDB.m. PC will get xxxann.mat for Y and xxxdata.mat for X.
For input data to keras conveniently, Segmentor.m will segment all recording into complexes and position of P-wave and R-wave is also saved in segmentors.mat.
if you load segmentor.mat into matlab. You will get segs with 96863 by 300 and anns with dimention of 96863 by 2 in workspace. That mean there are 96863 complexes with length of 300 sampling points.
ann[:,1] presents position of P-wave. ann[:,2] presents position of R-wave. More detail can be found in paper.
