Diagram illustrating the pathophysiology of preeclampsia, baroreceptor reflex response, and the implications on heart rate. We hypothesize that preeclampsia exerts its effects on heart rate primarily through baroreceptor reflex response to elevated blood pressure, leading to a decrease in heart rate. In addition, preeclampsia may be associated with end-organ damage that can lead to sympathetic stress response and an increase in heart rate.
