Postural Orthostatic Tachycardia Syndrome Clinical Trial
Official title:
Comparison of Effect of Propranolol, Bisoprolol, Pyridosgitmine in Postural Orthostatic Tachycardia Syndrome (POTS) and Prognosis After Medical Treatment
The purpose of the study is to investigate effect of medical treatment and prognosis of Postural Orthostatic Tachycardia Syndrome (POTS)
Many patients who complained of dizziness are eventually diagnosed as POTS. However, the
investigation of an appropriate medical treatment of POTS has not been enough yet. Also, the
prognosis of the disease after treatment is not well known. It is known that propranolol
attenuate the tachycardia and improve symptom burden in patients with POTS. However, the
effect of other β-Blocker, bisoprolol compared with propranolol is not known well. In
addition, acetylcholinesterase inhibition with pyridostigmine was a effective method of
acutely decreasing the tachycardia in patients with POTS. However, difference among three
medical treatments effect is not known and long-term studies are not done yet. Therefore, in
this study investigator investigate effect of medical treatment (propranolol only, bisoprolol
only, propranolol+pyridostigmine, bisoprolol+pyridostigmine) and prognosis of Postural
Orthostatic Tachycardia Syndrome.
Longer-term studies are needed to assess this promising therapy.
