  • Title: [The structural dynamics of vagus influence on the heart rhythm in exposures directed at altering the acting acetylcholine concentration].
    Author: Pokrovskiĭ VM, Osadchiĭ OE.
    Journal: Biull Eksp Biol Med; 1992 Dec; 114(12):570-3. PubMed ID: 1292673.
    Abstract:
    In 29 experiments on anaesthetized cats burst stimulation of peripheral cut end of right vagus nerve leads to synchronization of heart and vagus rhythm. Influence of proserine, pilocarpine and prolonged vagus stimulation upon extent of vagus chronotropic effect and its components--tonic and synchronizing--was investigated. In all cases changes of vagus chronotropic effect during this actions were caused by unidirectional shifts of tonic component. Extent of synchronizing vagus chronotropic influences did not depend on the changes of acetylcholine concentration.
