Pumping function of the heart ventricles under conditions of electrical stimulation was examined in adult dogs and rabbits. Pacing induced different changes in intracardiac hemodynamics manifested in impairment of pumping function of the right ventricle, which is largely determined by the functional state of the left ventricle. Initially high HR in rabbits more deeply limited functional reserve of the myocardium in response to electrical stimulus and was accompanied by more pronounced disturbances of pumping function of both ventricles.
