Postural tachycardia syndrome (POTS) is a form of orthostatic intolerance, the development of symptoms that come on when standing up from a reclining position, and that may be relieved by sitting or lying back down. The primary symptom of an orthostatic intolerance is lightheadedness, fainting and an uncomfortable, rapid increase in heartbeat (tachycardia), a common response to a rapid drop in blood pressure as mediated by baroreceptors in the carotid bulb and aortic arch. There are several inconstant secondary symptoms. A syndrome is simply a constellation of symptoms, not all of which may be present in all cases, and as is the case in POTS, a syndrome may also have a wide variety of underlying causes. A subset of POTS patients suffer from a low blood volume. Would you predict that this particular subset of patients has elevated or suppressed plasma levels of renin and aldosterone? Explain your answer. The nuance of dysregulation of the RAA axis is complex in these patients,…
