What is the long-term outlook for people with Brugada syndrome?

The long-term outlook (prognosis) for people with Brugada syndrome varies because the condition is very unpredictable. The condition manifests primarily during adulthood, and affected people have a high risk of ventricular arrhythmias and sudden death. The average age of sudden death is approximately 40 years.[1][2] Males with easily-induced sustained ventricular arrhythmias, and a spontaneously abnormal ECG, have a poor prognosis (a 45% likelihood of having an arrhythmic event at any time during life). Although Brugada syndrome is more common in males, females can be affected also and they too are at risk for sudden death.[2]
