title: [The reactions of the cardiorespiratory system to exposure to a hyperbaric environment in the simulation of free-ascent conditions].
abstract: In 44 adult rabbits simulating 360 to 700-m ascent, bradyarrhythmia, auricular extrasystoles, partial antegrade block, dyspnea and transitory apnoea were found. Changes in the R-R histograms as well as autocorrelation function and spectrum of the cardiointervalogram showed overstrain and exhaustion of the cardiac rhythm control system at the end of decompression. Mechanisms of the cardiorespiratory system's responses to hyperbaric ambient conditions are discussed.
