Features of Heart Rate Variability in Women of the Second Period of Adulthood Associated with the Body Weight

Resumo

The spectral parameters of heart rate variability (HRV) and systolic and diastolic blood pressures in apparently healthy female patients of the second period of adulthood have been analyzed. The mean values of the circulatory indices, total spectrum power (TP), absolute and relative values of the wave power in the very-low-frequency (VLF, %VLF), low-frequency (LF, %LF), and high-frequency (HF, %HF) ranges of the spectrum have been estimated. The HRV in women of the second period of adulthood with an increased body fat mass and obesity was characterized by an increase in the parasympathetic component of the autonomic nervous system. The increase in parasympathetic activity was associated with a decrease in heart rate in the group of women with abdominal obesity. A statistically significant negative correlation was found between the LF/HF index and fat mass.
