Brugada syndrome is a rare heart condition that's usually inherited. It can affect your heart rhythm and can be life-threatening, but there are things you can do to reduce the risk of serious problems.
Brugada syndrome does not usually cause any symptoms. Sometimes it's found when you have an electrocardiogram (ECG) for another reason.
If you do get symptoms they can include:
Symptoms usually start in adulthood, but it can happen at any age.
Brugada syndrome can also cause a dangerously fast or irregular heartbeat. This can lead to a cardiac arrest, where your heart beats so fast that not enough blood gets to your brain, so you become unconscious and stop breathing.
Follow the instructions from the 999 operator until an ambulance arrives.
You've been diagnosed with Brugada syndrome or you're worried you have it and:
Also ask for an urgent GP appointment if your parent, child, brother or sister has been diagnosed with Brugada syndrome, or died unexpectedly (you may also need tests to check your heart).
You can call 111 or get help from 111 online.
If a GP thinks you could have Brugada syndrome or another heart condition they'll refer you to a heart specialist (cardiologist).
You'll have tests such as:
As Brugada syndrome is usually inherited, you may also be offered genetic testing to see if you have genes linked to the condition.
If you're diagnosed with Brugada syndrome, your immediate family should also be offered testing as there's a chance they could also have the condition.
If you have Brugada syndrome but you've not had any symptoms, you will not usually need any medical treatment. Most people with the condition have a low risk of serious problems.
You'll be monitored regularly to check the health of your heart.
Doctors may recommend that you're fitted with an implantable cardioverter defibrillator (ICD).
This is a small device that's put under your skin in your chest, in a similar way to a pacemaker. It monitors your heart rhythm and sends an electrical shock to your heart when it's needed to correct the rhythm.
You'll only need an ICD if either:
If you have Brugada syndrome it's important to avoid triggers that can cause problems with your heart rhythm. Your care team will give you advice about this.
check with a doctor or pharmacist before taking any medicines – some medicines can cause problems in people with Brugada syndrome
take paracetamol or ibuprofen to help prevent a high temperature if you're unwell
do not drink too much alcohol – keep to the recommended guidelines of no more than 14 units a week, spread over 3 days or more
do not get dehydrated – you may need rehydration solutions if you're being sick or have diarrhoea
do not take part in very strenuous exercise or sports
You may be advised to go to A&E to be monitored.
You can call 111 or get help from 111 online.
Brugada syndrome is usually caused by the genes you inherit from your parents.
Less commonly, it can be caused by:
It's more common in men and in people of south east Asian origin.
If you or someone in your family has Brugada syndrome you can get help and support from charities, including:
If you have Brugada syndrome, your care team will pass information on to the National Congenital Anomaly and Rare Disease Registration Service (NCARDRS).
This helps scientists look for better ways to prevent and treat this condition. You can opt out of the register at any time.
