Key result
Electrolyte imbalance and pH alterations should be considered in patients with ST elevation, as they can cause a Brugada phenocopy requiring an Ajmaline test for confirmation.
Electrolyte imbalances such as hyperkalemia should be considered as a potential cause of ST-segment elevation and Brugada phenocopies before pursuing interventional treatments.
• Every ST segment elevation is suspicious of acute myocardial infarction and the diagnosis should be reached in a short time. • Electrolyte imbalance (i.e. hyperkaliemia) and Ph alterations should always be considered. • The treatment of electrolyte imbalance should be performed promptly, even before considering interventional treatments. • Brugada syndrome should be considered as a diagnosis, especially in patients with syncope and a coved type ST elevation in the right precordial leads. • Even a diagnostic type 1 Brugada pattern could be a phenocopy due to electrolyte imbalance. • When Brugada syndrome is presumed and electrolyte imbalance is present, an Ajmaline test is required to confirm the diagnosis.

Cornara et al. (2021) studied ST elevation, electrolyte imbalance, Brugada syndrome. Electrolyte imbalance and pH alterations should be considered in patients with ST elevation, as they can cause a Brugada phenocopy requiring an Ajmaline test for confirmation.
