Fever-induced ST-segment elevation in a syncopal patient with Brugada syndrome

Brugada syndrome (BS) is associated with life-threatening ventricular tachyarrhythmias. Although a diagnosis of BS can be made by typical electrocardiographic (ECG) findings, these findings for BS vary depending on the patients' physiological conditions and are sometimes normalized or less evident. It is important for emergency physicians to recognize that the typical electrocardiographic findings of BS are not always manifested but sometimes are only unmasked in the presence of a specific condition.
