[The effect of endogenous enkephalins on the phenomenon of the synchronization of vagus and cardiac rhythms]

[Article in Russian]


The effect of met- and leu-enkephalins in cats was characterised by depressing vagotropic action due to a selective decrease in the tonic component. The potentiation of synchronizing actions may serve as an index of a reliable and stable mechanism of the beat-by-beat control of the cardiac rhythm.
