The long and winding road of postural orthostatic tachycardia syndrome

Postural orthostatic tachycardia syndrome (POTS) is widely described as a chronic disorder of cardiovascular autonomic regulation, characterized by an exaggerated increase in heart rate upon standing [1]. The condition disproportionately affects women of reproductive age [2]. However, the clinical manifestations of POTS extend far beyond the cardiovascular system. Patients frequently experience a broad spectrum of symptoms, including exercise intolerance, cognitive difficulties such as impaired memory and concentration, gastrointestinal disturbances, and sleep disruption—often as prominently as palpitations and orthostatic intolerance [3].

Despite its substantial impact on quality of life, the long-term trajectory of POTS remains uncertain: Is it a lifelong condition or one from which patients may recover spontaneously?
