NPY Rreceptors Participate in the Change of Electrical Activity of Working Cardiomyocytes of the Right Atrium and Ventricle of Newborn Rats

© 2020 Russian Academy of Sciences, Institute of Archaeology. All rights reserved. We studied the effect of neuropeptide Y in concentrations 10-10-10-6M on the parameters of the electrical activity of cardiomyocytes of the right atrium and the right ventricle of 7-day-old rats. The effect of neuro-peptide Y on the duration of the phase of repolarization of the action potential was established. Neuropeptide Y reduced the duration of the repolarization phase in 7-days rats at concentrations 10-8and 10-7M and did not change the membrane potential and the duration of the depolarization phase in newborn rat pups.
