[Cardiogenic influences on the blood circulation].

The nature of cardiogenic influences on the circulation and the sensitivity of cardiac receptors to several substances after local immune damage of the heart, were studied: 30 min. after immune damage of the heart the depressor reflexes from the heart disappeared, and afferent impulse vagal activity was decreased. After immune damage of the heart, cardiac sympathetic afferent fibres are more sensitive to endogenous biologically active substances that vagal ones. The sympathetic cardiac afferent system seems to be more sensitive to chemical agent, being a decisive factor in the form of cardiogenic influences on the circulation during pathological processes in the heart.
