  • Title: [Role of the temperature factor in determining the nature of the chronotropic response of the heart of cats in the simulation of increased venous inflow].

    Journal: Nauchnye Doki Vyss Shkoly Biol Nauki; 1984; (11):52-4. PubMed ID: 6525375.
    Abstract:
    The heart rate changes in response to the imitation of venous input to the heart by infusion of an additional blood volume to the right atria have been studied on anesthetized by chloralose cats. It has been discovered that patterns of the heart rate changes are determined by the infused blood temperature if it is equal to the blood temperature in heart, tachycardia appears, if it is below this temperature, bradycardia develops. These data explain, from our point of view, the contradictory results obtaining by different authors in experiments with the imitation of the increased venous input (Bainbridge reflex).
