Fever Unveils the Hidden Danger: A Case Report of Brugada Pattern Unmasked by Pyrexia

Brugada syndrome (BS) is rare and potentially lethal arrhythmogenic disorder characterized by specific electrocardiographic abnormalities, which are often seen as the Brugada pattern. In the case report presented, a patient who had no history of syncope or documented arrhythmias experienced a febrile episode that precipitated the sudden appearance of Brugada-like ECG changes. This occurrence underscores the need for clinicians to remain vigilant for BS in febrile patients, even in the absence of prior cardiac findings. The typical ECG features of Brugada syndrome are more prominent during febrile illnesses, likely due to the inflammatory response and electrolyte disturbances associated with fever, which can trigger or reveal Brugada syndrome ECG patterns in individuals at risk. Detecting an increased risk of dysrhythmia in these patients is crucial, as it appears to be linked to a higher likelihood of in-hospital mortality.
