The Bainbridge reflex or Bainbridge effect (also called the atrial reflex) is a cardiovascular reflex causing an increase in heart rate in response to increased stretching of the wall of the right atrium due to increased filling of the right atrium with venous blood.
Jul 11, 2023 · The Bainbridge reflex is a compensatory reflex resulting in an increase in heart rate following an increase in cardiac preload.[1] Scientist Sir Arthur Bainbridge first demonstrated this reflex in unconscious anesthetized dogs with the monitoring of venous pressure, pulse rate, and arterial pressure following administration of blood or saline.[2]
Jul 15, 2011 · The Bainbridge reflex is invoked throughout the anesthesia literature to describe the effect of changes in venous return on heart rate in patients in the surgical and critical care settings, but a critical analysis of the experimental and clinical evidence is lacking.
Jul 11, 2023 · The Bainbridge reflex is a compensatory reflex resulting in an increase in heart rate following an increase in cardiac preload. Scientist Sir Arthur Bainbridge first demonstrated this reflex in unconscious anesthetized dogs with the monitoring of venous pressure, pulse rate, and arterial pressure fo ….
Bainbridge reflex, acceleration of the heart rate resulting from increased blood pressure in, or increased distension of, the large systemic veins and the right upper chamber of the heart. This reflex, first described by the British physiologist Francis Arthur Bainbridge in 1915, prevents the.
Aug 9, 2023 · Explore the comprehensive physiology of the Bainbridge reflex, including its anatomy, mechanisms, and clinical implications. Gain insights into how the Bainbridge reflex modulates heart rate and cardiac contractility in response to changes in venous return, contributing to cardiovascular homeostasis.
Sep 20, 2022 · Originally, the positive chronotropic response to stretch seen by Bainbridge was thought to occur solely through an extracardiac, centrally mediated reflex, as it could be abolished by transection of the vagi and cardiac sympathetic nerves and ligation of the suprarenal veins (ruling out a major role for circulating catecholamines from the ...
A "reverse" Bainbridge reflex has been proposed to explain the decreases in heart rate observed under conditions in which venous return is reduced, such as during spinal and epidural anesthesia, controlled hypotension, and severe hemorrhage.
Sep 29, 2021 · The Bainbridge reflex is a compensatory reflex resulting in an increase in heart rate following an increase in cardiac preload. Scientist Sir Arthur Bainbridge first demonstrated this reflex in unconscious anesthetized dogs with the monitoring of venous pressure, pulse rate, and arterial pressure following administration of blood or saline.
Aug 15, 2020 · Logically, the presence of the Bainbridge reflex (which increases heart rate in response to volume loading) should be matched by the presence of a "reverse Bainbridge" reflex which decreases the heart rate in response to decreased preload.
