[Age-Related Changes of Heart Rate Variability at Various Insulin Sensitivity and Telomere Length].

Aim: To study relationship between age-associated changes of heart rate variability (HRV), telomere length (TL), and lowering of insulin sensitivity (IS).

Material And Methods: We included in this study 229 individuals aged 23‒91 years without clinical manifestations of cardiovascular and other somatic diseases. In all participants, we analyzed HRV parameters obtained at 24-hour ECG monitoring (24-h ECG) and 5 minutes ECG recordings in the supine and standing positions.
