Postural orthostatic tachycardic syndrome

Matthew D Pierson, Andrew J Muzyk, Megan Lockamy, Xavier A Preud'homme
BACKGROUND: Topiramate is an anticonvulsant medication commonly used for a variety of neurological disorders including migraine prophylaxis. Broadened use of topiramate has brought an increased awareness of toxicity from this medication, particularly central nervous system side effects and metabolic acidosis. OBJECTIVE: We describe a case of topiramate toxicity occurring in a 22-year-old female following the ingestion of two 200 mg tablets, which she was prescribed for the treatment of migraines...

Postural orthostatic tachycardia syndrome encompasses a group of disorders characterized by orthostatic intolerance. We describe the anaesthetic management of analgesia for labour and of Caesarean section in a parturient suffering from this disorder. Worsening of her symptoms during pregnancy was managed with an increase in the dose of beta-blockers taken by the patient. Epidural analgesia was instigated early to attenuate the stress of labour and avoid consequent triggering of a tachycardic response. Slow titration of epidural analgesia and anaesthesia after an adequate fluid preload was undertaken to minimize hypotension and subsequent tachycardia...

OBJECTIVES: To demonstrate the association between orthostatic intolerance and the chronic fatigue syndrome (CFS) in adolescents and to delineate the form that orthostatic intolerance takes in these children. STUDY DESIGN: We investigated the heart rate and blood pressure (BP) responses to head-up tilt (HUT) in 26 adolescents aged 11 to 19 years with CFS compared with responses in adolescents referred for the evaluation of simple faint and to responses in 13 normal healthy control children of similar age...

PURPOSE: Orthostatic intolerance is the cause of significant disability in otherwise normal patients. Orthostatic tachycardia is usually the dominant hemodynamic abnormality, but symptoms may include dizziness, visual changes, discomfort in the head or neck, poor concentration, fatigue, palpitations, tremulousness, anxiety and, in some cases, syncope. It is the most common disorder of blood pressure regulation after essential hypertension. There is a predilection for younger rather than older adults and for women more than men...
