[The energy-informational role of the right ventricle in the informational-thermodynamic system of the heart].

Criteria for estimation of the energy-informational requirements of the right and left ventricles have been obtained using morphological data of the chronobiological experiment performed at Pathophysiology Chair of the RPFU in 1984. The estimates, due to greater energy-informational support of the right ventricle, demonstrate the leading role of the right ventricle, in regulation of the heart's informational-thermodynamic system (ITDS). The role of the left ventricle consists in maintenance of the heart contractility. Therefore, the left ventricle can function at lower energo-informational potential. These findings provide new evidence on internal mechanisms of the right and left ventricle dysfunction which could necessitate corrections of relevant diagnostic and therapeutic approaches.
