Baroreflex sensitivity

Baroreflex sensitivity refers to the responsiveness of the baroreceptors in the cardiovascular system to changes in blood pressure, facilitating adjustments in heart rate and vascular tone. It is clinically significant as reduced sensitivity can indicate autonomic dysfunction, often seen in conditions like hypertension and heart failure, leading to increased cardiovascular risk. For example, impaired baroreflex sensitivity is associated with higher rates of arrhythmias and adverse cardiovascular events.
