AECG is not only expanding the boundaries of traditional ECG, but is an important tool for assessing regulatory systems in their daily measurement, the use of which - no simple matter.
Standards of regulatory systems are not just tend to sex, age and environmental conditions have a clear seasonal pattern change during the day due to the natural activity ... They are extremely individual as each of us is different with the top personality in the psychological I.
One of the tools in the AECG, which measures the regulatory system is the heart rate variability (HRV).
Standards of HRV in healthy
high individual at rest and transient;
increase the total power of the HRV spectrum modulation of breathing and fall - in orthostatic reactions due to changes in the prevailing power of the high frequency component;
absence of gender (sex) differences in heart rate greater in females;
reduction of the total spectral power of HRV with age due to more quickly lower power high-frequency component;
lower weight - higher, higher weight - lower total power and power High-frequency component of HRV spectrum with higher and, consequently, lower respiratory reactions to metronomizatsiyu and active orthostasis;
Circadian changes in the spectral parameters of HRV with the growth of the total power spectrum due to the high frequency component of the night and fall due to the relative increase capacity of low-and mid-frequency components in the fall - high-frequency component;
increase the total power of the HRV spectrum with increasing power of high-frequency component of the active physical life with orientation to cyclical exercise;
total power falling HRV spectrum power is reduced when the active high-frequency component of mental activity coupled with low physical activity.
