Postural orthostatic tachycardia syndrome is a poorly understood autonomic disturbance, which manifests as tachycardia upon the patient standing erect from supine or a head-up tilt without underlying orthostatic hypotension. Sympathetic hyperstimulation secondary to a fall in vascular tone and cerebral hypoperfusion leads to symptoms such as inappropriate sinus tachycardia, chronic fatigue and dizziness.

Overview

Postural orthostatic tachycardia syndrome is a poorly understood autonomic disturbance, which manifests as tachycardia upon the patient standing erect from supine or a head-up tilt without underlying orthostatic hypotension. Sympathetic hyperstimulation secondary to a fall in vascular tone and cerebral hypoperfusion leads to symptoms such as inappropriate sinus tachycardia, chronic fatigue and dizziness.
