An interesting fact is that many of the persons experience arrhythmias in Brugada syndrome with fever.

Ventricular tachycardia is a potentially life threatening cardiac arrhythmia. Chronic recurrent monomorphic VT like fascicular tachycardia and right ventricular outflow tract tachycardia are also amenable to electrophysiological mapping and ablation. If the rate is very fast, hemodynamic deterioration can occur rapidly.

Prior to Mizusawa's study, it was thought that the incidence of syncope, arrhythmia, or SCD in this cohort was low [7]. In light of the risk of arrhythmia events observed in the Mizusawa trial, a formal EP study might be reasonable to obtain in those with fever induced asymptomatic Brugada ECG changes to help risk stratify these patients.
