Alternative tests to the tilt table test are also used, such as the NASA Lean Test [75] and the adapted Autonomic Profile (aAP) [76] which require less equipment to complete.There may be a loss of neurovascular coupling and reduced functional hyperemia in response to cognitive challenge under orthostatic stress – perhaps related to a loss of autoregulatory buffering of beat-by-beat fluctuations in arterial blood flow. [47] Causes [ edit ] Aggravating factors include exertion (81%), continued standing (80%), heat (79%), and after meals (42%). [84] Medication [ edit ] a b Busmer L (2011).

There is an increasing number of studies indicating that POTS is an autoimmune disease. [51] [5] [56] [3] [57] [58] A high number of patients has elevated levels of autoantibodies against the adrenergic alpha 1 receptor and against the muscarinic acetylcholine M4 receptor.

[28] The average age for POTS onset is 20 years old, and it occurs about five times more frequently in females than in males.

Clinical trial number NCT00409435 for "A Study of Pyridostigmine in Postural Tachycardia Syndrome" at ClinicalTrials.gov When changing to an upright posture, finishing a meal, or concluding exercise, a sustained hand grip can briefly raise the blood pressure, possibly reducing symptoms. [34] Compression garments can also be of benefit by constricting blood pressures with external body pressure. [34] Associated with related symptoms that are worse with upright posture and that improve with recumbence. Crnošija L, Krbot Skorić M, Adamec I, Lovrić M, Junaković A, Mišmaš A, etal.
