title: [Characterization of cardiovascular system function in children from the Issyk-Kul Rregion].
abstract: The age-specific features of the cardiovascular system in a child and the pattern of adaptive responses to the long-term impact the mountain-and-maritime climate of the Issyk-Kul Region. All the children were found to have bradycardia (43-61 beats per min), which corresponds to the parasympathetic predominance of their nervous system. They also showed a short pulse recovery (60 seconds), unlike the children of the plains and a statistically significant pulse rate reduction at rest minute 5 (p < 0.05) as compared with the base-line level. In the settlement of Kadji-Sai, there was a decrease in all functional parameters: pressure, the time of a response to light and sound stimuli. It was ascertained that the following features were characteristic for mountain dwellers: bradycardia associated with the predominance of the parasympathetic nervous system and the tendency towards lowered systolic pressure without a significant change in diastolic pressure.
