Classification and prediction of heart disease is a significant problem to realize medical treatment and life protection. In this paper, persistent homology is involved to analyze electrocardiograms and a novel heart disease classification method is proposed. Each electrocardiogram becomes a point cloud by sliding windows and fast Fourier transform embedding. The obtained point cloud reveals periodicity and stability characteristics of electrocardiograms. By persistent homology, three features including normalized persistent entropy, maximum life of time and maximum life of Betty number are extracted. These features show the structural differences between different types of electrocardiograms and display encouraging potentiality in classification of heart disease.
