Evidence for Impaired Renin Activity in Postural Orthostatic Tachycardia Syndrome
Background: Postural orthostatic tachycardia syndrome (POTS) is a heterogeneous condition predominantly affecting autonomic control of the cardiovascular system. Its extensive symptom diversity implies multi-organ involvement that interacts in ways still requiring full exploration. Current understanding of POTS pathophysiology suggests alterations in the renin–angiotensin–aldosterone system as a p
