==Diagnosis and treatment==
*Patients who are symptomatic (unexplained
syncope, ventricular tachycardias or survivors of sudden cardiac death) have a mortality risk of up to 10% per year. In these patients an [[:w:nl:Internal_Cardiac_Defibrillator|ICD]] is adviced to be implanted. *Some groups advice an electrophysiological investigation (inducibility of VF) for risk assessment in Brugada patients,<cite>brug2</cite><cite>brug3</cite> but others could not reproduce the predictive value of these tests,<cite>priori</cite><cite>eckhardt</cite> so the value of inducibility is (very) controversial.
*In large studies familial sudden death did not appear to be a risk factor for sudden death in siblings.
*In asymptomatic patients in whom the Brugada ECG characteristics are present (either spontaneously or provoked by fever or sodium channel blockers like ajmaline, procainimde or flecainide) life style advices are given, which include:
**A number of medications should not be taken (amongst which
beta-blockers, and sodium channel blockers such as certain anti-depressants and anti-arrhythmics)
**Rigorous treatment of fever with paracetamol / Tylenol, as fever may elicited the Brugada ECG and arrhythmias in some patients.
* Spontaneous Type I ECGs do
however appear to be more prevalent in patients who experienced symptoms.
