title: Not all ST-segment elevations are myocardial infarction: Hyperkalemia and Brugada phenocopy.
abstract: Several clinical conditions other than Brugada syndrome (BrS) can mimic acute ST-segment elevation myocardial infarction and Brugada phenocopies are a part of those conditions that can mimic either true BrS or acute myocardial infarction. Our manuscript shows an interesting and didactic case report of type-1 Class A Brugada phenocopy (BrP) induced by hyperkalemia and allow us to teach the systematic approach to the proper diagnosis of BrP. A prompt recognition of this clinical and electrocardiographic entity may expedite the initiation of appropriate treatments as illustrated in this case report.
