Fever-Induced Type 1 ECG Pattern of Brugada Syndrome

A 38-year-old female  presented to the emergency department with symptoms and signs of an upper respiratory infection. ECG on admission performed during febrile state (38.8°C) revealed the diagnostic type 1 ECG pattern of Brugada syndrome. Two hours later, a new ECG performed without fever failed to show any of these abnormalities. Due to the increased risk of ventricular arrhythmias during febrile state, fever should be vigorously treated with antipyretics in these patients.
