The Effect of Metabolic Syndrome Factors on the Change in Cardiac Rhythm Variability
The aim of the research is to assess the effect of metabolic syndrome factors on the change in cardiac rhythm variability.
Materials and Methods. There have been studied the factors of metabolic syndrome, cardiac rhythm variability indexes, and diastolic dysfunction of the left ventricle in 320 patients without ischemic heart disease.
Results. In patients with metabolic syndrome, the decrease of cardiac rhythm variability manifesting as the tonus reduction of parasympathetic and sympathetic parts of vegetative nervous system was stated to be due to obesity. Obesity regardless of the presence of metabolic syndrome in patients is associated with displacement of vegetative nervous system balance towards the prevalence of tonus of the sympathetic part for account of tonus reduction of parasympathetic part, as well as with the development of diastolic dysfunction of the left ventricle.
