[The right heart ventricle during hemodynamic overload of the left ventricle].

Two types of hemodynamic overload were simulated in rabbits: renovascular arterial hypertension by the Goldblatt method and the half coarctation of the ascending aorta versus the baseline diameter. The functional indices and ultrastructure of the left and right ventricles were studied in different periods of these processes. If the left ventricle is hemodynamically overloaded, the right one immediately takes part in the process and then largely governs the performance dynamics of the whole heart.
