Impaired blood pressure regulation in post-COVID-19 postural orthostatic tachycardia syndrome: novel disease mechanisms beyond sinus tachycardia
Background: Postural orthostatic tachycardia syndrome (POTS) is a prevalent cardiovascular disorder after COVID-19 infection. Although POTS is characterized by the presence of sinus tachycardia, other hemodynamic disturbances including blood pressure (BP) regulation, remain largely unexplored.Aims: We investigated BP changes using 24-hour ambulatory-BP-monitoring in patients with new-onset POTS af
