title: Brugada Phenocopy Induced by Electrolyte Disorder: A Transient Electrocardiographic Sign.
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.
