[Functional characteristics of the different types of heart receptors].
A methodical procedure for the study of receptors was elaborated by means of which three types of nerve endings were detected and differentiated in the heart: mechano-, chemo-, and polymodal receptors. A difference was determined between them by the form of the reaction to mechanical (hemodynamic) and chemical stimulation of the heart. The polymodal receptors are characterized by a mixed form of reaction providing for the integration of sensory polyvalence.
