Hyperkalaemia is a potentially fatal clinical problem frequently seen in the emergency department (ED). It causes a spectrum of electrocardiogram (ECG) changes such as peaked T-waves, prolonged PR interval, widened QRS complexes, intraventricular/fascicular/bundle branch blocks, etc. Brugada Phenocopy (BrP) is a rare ECG finding seen in severe hyperkalaemia associated with the prevalence of malignant cardiac arrhythmias and all-cause mortality. Unlike Brugada Syndrome (BrS) it is a transient phenomenon and completely resolves with the normalization of hyperkalaemia. Here we report a Brugada Phenocopy (BrP) case observed in a middle-aged male with severe hyperkalaemia.
高钾血症是急诊科（ED）中经常出现的一种潜在致命临床问题。它会引起一系列心电图（ECG）改变，如尖峰 T 波、PR 间期延长、QRS 波群增宽、室内/束支/分支阻滞等。Brugada 表型（BrP）是一种罕见的 ECG 表现，见于与恶性心律失常和全因死亡率相关的严重高钾血症。与 Brugada 综合征（BrS）不同，它是一种短暂的现象，随着高钾血症的正常化而完全消失。在这里，我们报告了一名中年男性严重高钾血症时出现的 Brugada 表型（BrP）病例。
