Background: The baroreflex normally serves to compensate for excessive rise or fall of blood pressure. Baroreflex failure occurs when afferent baroreceptive nerves or their central connections become impaired. In baroreflex failure, there is loss of buffering ability, and wide excursions of pressure and heart rate occur. Impairment of the baroreflex may produce an unusually broad spectrum of clinical presentations; with acute baroreflex failure, a hypertensive crisis is the most common presentation. In the absence of an acute event, volatile hypertension with periods of hypotension may occur. Abnormalities in th…
