Acetylcholinesterase inhibition improves tachycardia in postural tachycardia syndrome.
BACKGROUND Postural tachycardia syndrome (POTS) induces disabling chronic orthostatic intolerance notable for an excessive increase in heart rate that occurs on standing. Many current therapeutic strategies focus on sympatholysis, but the alternative strategy of enhancing cardiovagal tone has not been studied. The objective of this study was to test the hypothesis that acetylcholinesterase inhi...
متن کاملAscorbate improves circulation in postural tachycardia syndrome.
Low flow postural tachycardia syndrome (LFP) is associated with vasoconstriction, reduced cardiac output, increased plasma angiotensin II, reduced bioavailable nitric oxide (NO), and oxidative stress. We tested whether ascorbate would improve cutaneous NO and reduce vasoconstriction when delivered systemically. We used local cutaneous heating to 42°C and laser Doppler flowmetry to assess NO-dep...
متن کاملPostural tachycardia syndrome (POTS).
INTRODUCTION POTS is defined as the development of orthostatic symptoms associated with a heart rate (HR) increment >or=30, usually to >or=120 bpm without orthostatic hypotension. Symptoms of orthostatic intolerance are those due to brain hypoperfusion and those due to sympathetic overaction. METHODS We provide a review of POTS based primarily on work from the Mayo Clinic. RESULTS Females p...

متن کاملPostural tachycardia syndrome.
Case Presentation: A 34-year-old woman had been well until 9 months previously when, after a febrile illness, she developed palpitations, fatigue, exercise intolerance, dyspnea on exertion, and frequent episodes of lightheadedness and near syncope. ECG, echocardiogram, and endocrine evaluation were all normal. On physical examination, she displayed a postural increase of 35 bpm on standing, alo...
