Heart rate turbulence and heart rate variability in persons with various blood pressure

Aim. The article deals with factor and regression analysis of heart rate variability and heart rate turbulence during Holter monitoring in persons with various blood pressure. Materials and methods. 68 persons aged 56.21 ± 1.06 participated in the study (48.5% female participants). We analyzed 24-hour ECG recordings obtained with the help of a Holter monitor and hardware software complex ‘Kardiotekhnika-04’ (INCART). The results obtained were interpreted using a standard diagnostic scheme proposed by the Russian society of cardiology in 2013. We also assessed heart rate turbulence and heart rate variability using a standard procedure. We used the methods of descriptive statistics to process continuous numerical data. We studied continuous and interval variables with the help of factor analysis and used the data obtained to conduct regression analysis. Results. The analysis revealed that the variables studied depend on each other, while the most important factor is, obviously, arterial blood pressure. Conclusion. The results obtained prove that the main reason of heart rate variability and heart rate turbulence is an increase in arterial blood pressure.
