Influence of hypoxemic training on changes of microcirculation vessels in various parts of rats ' hearts

Intraorganic heterogeneity of changes in microcirculation vessels in heart at different stages of adaptation to intermittent hypoxia has been established. At early stages (1–7 days) the reactivity of microcirculation vessels is increased in all right ventricle. As the validity of intermittent hyperbaric hypoxia grows the reaction of microvessels in left ventricle decreases (15 days). The reaction remains rather high in myocard of right ventricle and interventricular septum.
