Abstract
Brugada syndrome (BrS) is an important cause of sudden cardiac death (SCD) with well-defined ST-segment elevation patterns on V1 -V3 . Observation of BrS-Type-electrocardiogram (ECG) patterns in medical conditions without true BrS is called "Brugada Phenocopy" (BrP). We present a case of 61-year-old male patient with hyperkalemia, hyponatremia, and BrS-Type-1 ECG pattern in the setting of acute postrenal failure. He was denying any syncope or family history of SCD. With normalization of electrolyte levels, BrS-Type-1-ECG resolved. Electrolyte disturbances are one of the most common reasons of BrP. Being aware of BrPs and differentiating from an unmasked BrS-ECG pattern could prevent patients from lethal consequences and unnecessary treatments.
摘要
Brugada综合征（BrS）是心源性猝死（SCD）的重要原因，在V1 - V3导联有明确的ST段抬高模式。在没有真正BrS的疾病状态下观察到BrS型心电图（ECG）模式称为“Brugada拟表型”（BrP）。我们报告一例61岁男性患者，在急性肾后性肾衰竭背景下出现高钾血症、低钠血症及BrS 1型ECG模式。他否认有任何晕厥或SCD家族史。随着电解质水平恢复正常，BrS 1型ECG消失。电解质紊乱是BrP最常见的原因之一。认识BrP并与未掩盖的BrS ECG模式相鉴别可防止患者出现致命后果和不必要的治疗。
