[The regulation of human cardiac activity during the cyclical change of barometric pressure under sealed-cabin conditions].
A cyclic change of barometric pressure from 790 to 720 mm Hg once a day to twice within 3 days under sealed conditions results in a functional rearrangement of the mechanisms to control cardiac activity which cause the predominance of vagotonic responses determined by a decrease of the body reserves and its asthenization. At the beginning of staying under pressurized conditions (2nd week) it appears as an occurrence of meteorotropic responses (in 13% of subjects tested) and at the end of living in pressurized conditions (9th week) as a significant decline with a change ("removal") in: pressure, index of strain, vegetative index of rhythm, index of regulation processes, index of vegetative equilibrium and as an increase in the number of individuals responding to a cyclic change of barometric pressure up to 44% which is indicative of a moderate relationship between manifestation rate of these sensations and an effect duration of a given factor.
