title: [Heart rate variability in migrants to the North with hypertension comorbid with biliary diseases].
abstract: OBJECTIVE
  To study heart rate variability (HRV) in patients with biliary problems and hypertension depending on duration of their life in the North.
  
  
  METHODS
  A standardized screening of 1014 workers living in Mirny (Yakutia) according to the WHO/CINDI Euro regional committee program was performed.
  
  
  CONCLUSIONS
  With an increase of duration of living in the North patients with biliary diseases combined with arterial hypertension develop disorders of humoral-metabolic regulation mechanisms, increased parasympathetic activity, imbalance of the autonomic nervous system.
