This article considers the issues of analyzing ECG signals based on statistical methods. In the study, the main parameters obtained from electrocardiogram signals were evaluated using mathematical and statistical methods. In particular, the influence of ECG parameters on cardiac activity indicators was studied through regression analysis, and the degree of correlation between the parameters was determined using correlation analysis. Within the framework of variance analysis, the dispersion, standard deviation, and coefficient of variation were calculated and the signal distribution characteristics were evaluated. Also, the coefficient of determination, Student's criterion, Fisher's exact test, and Durbin–Watson criterion were used to check
