Postural orthostatic tachycardia syndrome
Orthostatic intolerance can be defi ned as inability to tolerate upright posture relieved by recumbence. Postural orthostatic tachycardia syndrome (POTS) is a form of orthostatic intolerance defi ned as sustained increase in heart rate of ≥30 bpm or increase of heart rate to ≥120 bpm within 10 min of standing or head-up tilt associated with symptoms of orthostatic intolerance and absence of ort...
متن کاملPeptides in Postural Orthostatic Tachycardia Syndrome
Recently, increasing attention has been directed toward better understanding the physiological role and clinical importance of a wide range of endogenously released vasoactive peptides. The most well known of these are B-type natriuretic peptide (BNP) and atrial natriuretic peptide (ANP) (1–4). However, others have also attracted attention, including C-type natriuretic peptide, vasoactive intes...
متن کاملSleep Characteristics in Postural Orthostatic Tachycardia Syndrome
Study Objectives: Patients with Postural Orthostatic Tachycardia Syndrome (POTS) complain of difficulties with sleep dysfunction. This study characterizes sleep architecture and Alpha-Delta sleep (ADS) in patients with POTS. Methods: Patients diagnosed with POTS with reported daytime sleepiness were evaluated by polysomnography (women=100%; mean age= 34.3; range 25-55). Measurements included nu...
متن کاملPostural orthostatic tachycardia syndrome following Lyme disease.
BACKGROUND A subgroup of patients suffering from Lyme disease (LD) may initially respond to antibiotics only to later develop a syndrome of fatigue, joint pain and cognitive dysfunction referred to as 'post treatment LD syndrome'. We report on a series of patients who developed autonomic dysfunction in the form of postural orthostatic tachycardia syndrome (POTS). METHODS All of the patients i...
متن کاملPostural orthostatic tachycardia syndrome: Dental treatment considerations.
BACKGROUND Postural orthostatic tachycardia syndrome (POTS) is a chronic, relatively common autonomic disorder typically affecting younger females. It is distinguished by a dramatic increase in heart rate on the assumption of an upright posture from the supine position. METHODS The authors provide an overview of the demographics, clinical assessment, diagnostic features, differential diagnose...
