*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.  
*Patients who are symptomatic (unexplained syncopes, ventricular tachycardias or aborted sudden cardiac death) may have a symptom recurrence risk of 2 to 10% per year. In these patients an [[:w:nl:Internal_Cardiac_Defibrillator|ICD]] is adviced to be implanted. Further, life-style advices are given (see below).
*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:
*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)
**A number of medications should not be taken (amongst which sodium channel blockers such as certain anti-depressants and anti-arrhythmics, see [http://www.brugadadrugs.org www.BrugadaDrugs.org])
**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.
