RESUMO

Descreveu-se a Síndrome da Taquicardia Postural Ortostática (POTS) em uma adolescente de 16 anos, com história de 10 anos de hipotireoidismo e episódio de síncope incompleta e sintomas disautonômicos flutuantes por seis meses. Após esses seis meses, a paciente apresentou novo episódio de síncope incompleta pós-prandial. Apesar de um Tilt Test não ter flagrado anormalidade, em duas ocasiões separadas, flagramos aumentos ortostáticos da frequência cardíaca de 43 e 40 bpm, sem queda significativa da pressão arterial. Além de hipotireoidismo, não se detectaram outros fatores de risco para disautonomia. Propranolol (10mg, 12/12h) controlou os sintomas. POTS é de difícil. (AU)


We describe the Postural Orthostatic Tachycardia Syndrome (POTS) in a 16-year-old girl with a 10-year history of hypothyroidism who experienced an incomplete syncope episode with fluctuating disautonomic symptoms for 6 months. After six months, the patient had a new postprandial incomplete syncope episode. Although a Tilt Test did not disclose abnormality, in two separate occasions, we documented a heart rate increase of 43 and 40 bpm after standing, without a significant drop in blood pressure. Other than hypothyroidism, we did not detect other risk factors for dysautonomia. Propranolol (10mg, 12 / 12h) controlled the symptoms. POTS is difficult to diagnose in adolescents. It is often confused with Epilepsy and Neurocardiogenic Syncope, which may result from hypothyroidism. (AU)

RESUMO

El vértigo fóbico se constituye como una patología dentro de las alteraciones somatomorfas que cursan con trastornos del balance, relacionadas a un proceso de desajuste sensorial aferente, con repercusiones eferentes especiales que no son evidentes al observador, identificadas, por ejemplo, por un aumento en los patrones de propiocepción detectados por electroposturografía. Las características clínicas de estos pacientes están descritas como eventos vertiginosos no asociados a claros desencadenantes, sino más bien una respuesta muy personal a ambientes particulares normales para otras personas, quienes adicionalmente ofrecen personalidades obsesivas-compulsivas, perfeccionistas autodemandantes, incluso depresivas dentro de un contexto que culmina en inestabilidad. No se identifican alteraciones auditivas concomitantes, ni tampoco neurológicas centrales, por lo que su diagnóstico diferencial podría hacerse evidente denotando los diagnósticos más relevantes, tanto psicogénicos como orgánicos, aportados por Brandt y colaboradores...


Phobic vertigo is constituted as a pathology within the somatoform disorders that causes balance disease related to a mismatch process between afferent signals and efferent sensorial perceptions with special effects that are not apparent to the observer, identified by cause an increase in proprioception patterns detected by electroposturography. The clinical characteristics of these patients are described as dizzying events not associated with clear triggers, but rather a very personal response to particular environments for them and normal for others; those obsessive compulsive personalities additionally can offer, auto-perfectionists, depressives feelings, within a context that culminates in instability. Are not identified concomitant hearing impairment, nor central neurological disease, differential diagnosis could be make evident, thanks to the most relevant both psychogenic and organic issues provided by Brandt et ál...

RESUMO

Background: Patients with postural orthostatic tachycardia syndrome (POTS) report dizziness, lightheadedness, weakness, blurred vision, and fatigue upon standing. The diagnosis of the syndrome is made when an orthostatic intolerance and tachycardia appear in the standing position. Aim: To report 15 patients with POTS. Material and Methods: Review of Tilt test reports in a period of 15 years. Those reports in which orthostatic postural tachycardia and symptoms compatible with POTS appeared, were selected for analysis. Results: We identified 15 patients (3.1% of all positive Tilt test reports) with compatible signs and symptoms. There was a lag of 8 -10 years between the onset of symptoms and the time of diagnosis. Most patients complained of orthostatic intolerance, dizziness and frequent fainting. Orthostatic tachycardia and symptoms occurred on average after 2.9 and 6.1 minutes, respectively,of staying in the standing position. These patients had a high frequency of family history of syncope orpresyncope (66% frequency) and hyper mobility syndrome (53% prevalence). Only 33% of the patients reported relief of their symptoms after being treated (most of them with fludrocortisone). Most patients that reported little or no relief, did not use medications or were treated for a short period. Conclusions: POTS syndrome is uncommon but disturbs quality of life of those who suffer it. Its association with hyper mobility syndromes must be investigated.
