Figure 1. Electrocardiogram (ECG) tracing in a 26-year-old male presenting with acute encephalopathy, acute hypoxic respiratory failure, and acute hyperkalemia, resulting in Brugada-like ECG changes. Top ECG tracing obtained while serum potassium measured 7.2 mmol/L, demonstrating the type 1 “coved” Brugada pattern with concave, ST-segment elevation most prominent in leads V1 and V2 (arrow). Bottom ECG tracing demonstrating resolution of ST-segment changes after correction of serum potassium to 4.4 mmol/L.
