Kuban Medical Institute, Krasnodar.


When stimulating the peripheral and of the right n. vagus in anesthetised cats, the sinus arrhythmia occurred in case the vagal bursts were beyond the limits of the controlled bradycardia range. I. v. administration of met-enkephaline suppressed the arrhythmia immediately but the latter reappeared within 15-20 minutes. The data obtained suggests a biphasic effect of met-enkephaline upon the vagal sinus arrhythmia.
