Brugada syndrome is an uncommon, but serious, heart condition. It can result in abnormally rapid heart rhythms called arrhythmias, which can cause palpitations or fainting and can be fatal.

However, some people with the condition have no symptoms at all.

Even though the heart pumps and looks normal, it's possible for sudden electrical activityto lead to a dangerous heart rhythm.

This problem can be genetic, or may be passed on in families see What's the cause? below.

Not everyone with Brugada syndrome experiences arrhythmia, but when it does happen, it can be fatal.
