Recognition of heart rhythm disorders in children by integral parameters of electrocardiograms

Abstract

The article deals with the organization of a database table for the accumulation of integral parameters of electrocardiograms of male and female children in the front-line region of residence (the city of Kharkiv and the Kharkiv region of Ukraine). The calculated main numerical characteristics of integral ECG parameters such as mathematical expectation, variance and standard deviation with heart rhythm disorders are presented. The application of logistic regression to determine the degree of heart rhythm disturbance, which is determined in the interval (0;1), is considered. Representation of logistic regression as multiple linear regression is described. The LSE method is used to estimate the parameters. A correlation matrix of linearly independent integral ECG parameters is given. The obtained results may be of interest to developers of software applications designed for personal health monitoring.
