A 78-year-old man presented to the emergency department with a 10-day history of diarrhea and presyncope. His electrocardiogram showed a type-1 Brugada pattern but also a first-degree atrioventricular block, right bundle branch block, and peaked and symmetrical hyperacute T waves. A blood test revealed a potassium level of 9.3 mEq/L. After hemodialysis with normalization of serum potassium, the electrocardiographic abnormalities disappeared. An ajmaline challenge excluded the possibility of Brugada syndrome.
一位 78 岁男性因腹泻和晕厥前兆 10 天到急诊就诊。他的心电图显示 1 型 Brugada 图形，但也存在一度房室传导阻滞、右束支阻滞和尖顶对称的超急性 T 波。血液检查显示血钾水平为 9.3mEq/L。经过血液透析使血清钾正常化后，心电图异常消失。阿马林激发试验排除了 Brugada 综合征的可能。
