Equilibrium disorders and R-R intervals in ECG.
We have measured RR intervals on patients with equilibrium disorders to check the function of the autonomic nervous system. And we have obtained two parameters (coefficient of variation "CV%" (the static function of the autonomic nervous system] and "A-B" (the dynamic function of the autonomic nervous system). The dynamic function of the autonomic nervous system (A-B) further deteriorated in elderly patients with central nervous system disorders. We concluded that disorders in the dynamic function of the autonomic nervous system affected the autoregulation which caused the central nervous system disorders, especially in elderly patients.
