Multifactor discriminant analysis of electrocardiograms at screening patients with ischemic heart disease

The aim of the study is to create a mathematical model of non-invasive diagnostics of coronary heart disease. Research materials include indicators of heart rate variability, time and speed characteristics of repolarization phase of electrocardiograms obtained in 111 patients with coronary heart disease and in 92 healthy individuals. As a result of the multifactor discriminant analysis decisive diagnostic rule has been worked out. The proposed method allows to detect coronary artery disease in 97.7% of cases
