Resumo(s)
O Padrão de Repolarização Precoce (PRPr) tem sido descrito desde há quase um século. Inicialmente, era visto como uma variante benigna da repolarização cardíaca, sobretudo em jovens. Contudo, nas últimas duas décadas surgiram evidências que este padrão está, claramente, associado a um risco acrescido para eventos disrítmicos e morte súbita cardíaca.
Neste trabalho apresenta-se o caso clínico de um jovem que recorreu ao Serviço de Urgência do Hospital de Santa Maria por palpitações e por síncope, observando-se no electrocardiograma PRPr.
A propósito deste caso clínico é feita uma revisão sistematizada sobre o tema, focando sobretudo a problemática da abordagem diagnóstica, da estratificação de risco e do tratamento da Síndrome de Repolarização Precoce.
Early Repolarization Pattern has been being described for nearly a century. Initially, it was considered as a benign variant of cardiac repolarization, especially in young people. However, in the last two decades, evidence has emerged suggesting that this pattern is clearly associated with an increased risk for dysrhythmic events and sudden cardiac death. In this work, we present the clinical case of a young man who recurred to the Emergency Department of Hospital de Santa Maria for palpitations and syncope and in whom was observed Early Repolarization Pattern on the electrocardiogram. A systematized review on the subject is done, focusing mainly on the diagnostic approach, the risk stratification and the treatment of the Early Repolarization Syndrome.
