title: [Mechanisms of changes in cardiac output during stimulation of afferent fibers of a somatic nerve].
abstract: In anesthetized cats, the technique of electromagnetic expenditure-metry aided to study changes of the cardiac output and venous inflow in pressor responses to stimulation of the tibial nerve's afferent fibers. The cardiac output was found to increase in 47% of observations which was accompanied by increased venous inflow in half of the cases and by decreased one in 1/3 of observations. Vagotomy as well as suppression of the efferent link of cardiac responses with atropin and obsidan induced shifts of the cardiac output in the somatic nerve stimulation. The optimum level of arterial pressure responses was revealed peculiar by positive shifts of the cardiac output in pressor responses to the above action.
