A 41-year-old man with Brugada syndrome (BS) and no previous episodes of aborted sudden death or syncope referred to local emergency room for an episode of symptomatic atrial fibrillation. Blood chemistry results showed hypokalemia (2.9 mEq/L). The other parameters were within the normal range. After few minutes, an episode of ventricular fibrillation treated with biphasic DC shock 150 J occurred. In successive 2 hours, the patient experienced recurrent episodes of ventricular tachycardia and fibrillation. Each biphasic DC shock 150 J was effective to restore sinus rhythm. No further episodes occurred after normalization of serum levels of potassium. Before discharge, an implantable cardioverter defibrillator was inserted to prevent sudden cardiac death. Hypokalemia increases the risk of arrhythmic events in BS.
一名41岁患有Brugada综合征（BS）且既往无心脏骤停或晕厥发作史的男性因症状性房颤发作被送往当地急诊室。血液化学检查结果显示低钾血症（2.9 mEq/L）。其他参数均在正常范围内。几分钟后，发生了室颤，给予150 J双相直流电除颤治疗。在接下来的2小时内，患者反复发作室性心动过速和室颤。每次150 J双相直流电除颤均有效恢复窦性心律。血钾水平恢复正常后未再发作。出院前，植入了植入式心脏复律除颤器以预防心源性猝死。低钾血症会增加BS患者发生心律失常事件的风险。
