This is a compensatory mechanism since 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 The Bainbridge reflex controls heart rate in response to blood volume. Stretch receptors are located in the right atrium, The atrial mechanoreceptors that activate the Bainbridge reflex send afferent signals via the vagus nerves to the medulla in the brain. Learn about It maintains blood pressure through feedback loops involving the vasomotor center in the medulla. It was noted as an increase in heart rate Small negative changes of central volume reduce cardiac output without significant alterations of arterial blood pressure (ABP), suggesting an adequate regulatory response.
