Suspected hyponatremia-induced Brugada phenocopy.

Area of Science:

• Cardiology
• Electrophysiology
• Internal Medicine

Background:

• Brugada syndrome is a genetic disorder associated with sudden cardiac death.
• Brugada phenocopy refers to the Brugada type 1 ECG pattern seen without the genetic syndrome.
• Factors inducing Brugada phenocopy are diverse, but literature on electrolyte disturbances is limited.

Observation:

• This case report focuses on a patient presenting with a Brugada type 1 ECG pattern.
• The patient's electrocardiogram abnormality was suspected to be induced by hyponatremia (low sodium levels).

Findings:

• The Brugada type 1 ECG pattern observed in the patient normalized after hyponatremia was corrected.
• This suggests a potential causal link between hyponatremia and the Brugada type 1 ECG pattern.

Implications:

• Hyponatremia should be considered as a potential reversible cause of Brugada phenocopy.
• This finding may impact the diagnostic and management strategies for patients with Brugada type 1 ECG patterns.
• Further research is warranted to explore the relationship between electrolyte imbalances and cardiac arrhythmias.
