Abstract

Administration of neurotensin against the background of sinus arrhythmia caused by burst stimulation of the vagus nerve in cats restores synchronization of the cardiac and vagal rhythms or modulates the proportion between them. This either stops the arrhythmia or changes its parameters. The effects of the peptide are similar to those of epinephrine and are abolished by β-adrenoreceptor blockage.
