Investigation of models for prognosis of critical values of non-invasive electrophysiological parameters of pregnant women with abnormalities of heart rate

摘要

The article presents the research materials on the development of models and methods for prognosis of critical values in the number and duration of atrial fibrillation for trimesters in pregnant women. The choice of cardiac activity characteristics, most influencing the predicted values, obtained in the framework of non-invasive electrophysiological studies, is substantiated. A new two-step method of selection of predictors for creation of models of electrophysiological parameters of heart prediction is proposed. It allows to identify the most valuable dependencies of target parameters. Based on the selected characteristics, a research is conducted to build several types of prediction models, and to determine the indicators of their effectiveness.
