title: [Influence of ethacizin (the diethyl analog of ethmozine) on phase-dependent parasympathetic effects on the heart].
abstract: The influence of ethacizin (a diethylamine analog of ethmozine) (1.10(-7)-1.10(-6) g/ml) upon the phase-dependent chronotropic parasympathetic effects was studied on the perfused frog heart. The vagolytic influence of ethacizin (5.10(-7) and 1.10(-6) g/ml) was detected; the concentration of 1.10(-7) g/ml was found ineffective. The vagolytic effect consisted of a decreased maximum of phase-dependent effect, reduced latency and time required for the manifestation of the maximum increase. The period of inhibitory vagal stimulus effectiveness did not change significantly.
