Hyperkalemia should be recognized as a potential trigger for acquired Brugada pattern with electrical alternans.
The Brugada syndrome is a genetic disease (mutation of the SCN5A gene) that predisposes to syncope and life-threatening sudden cardiac death. The case highlights the importance of recognizing hyperkalemia, as potential triggers of the acquired Brugada sign with electrical alternans.

Liu et al. (2012) conducted a case report in Hyperkalemia-induced Brugada pattern (n=1). Hyperkalemia was evaluated on Electrocardiographic changes. Severe hyperkalemia induced a dynamic Brugada electrocardiographic pattern with electrical alternans, which completely resolved upon correction of the electrolyte abnormality.
