Quick answer
Brugada syndrome is a rare inherited heart rhythm condition. Most of the danger comes from triggers: healthdirect lists fever, some medicines, alcohol and illicit drugs. So the people treating you need to know two things fast — that a fever must be brought down promptly, and that every new medicine needs checking first. A Brugada syndrome medical ID tells them, along with your ICD details and your cardiologist’s name.
Many people with Brugada syndrome feel completely well. The condition may have been found on a routine ECG, or after a relative was diagnosed. That is exactly why it is easy to miss in an emergency: there is nothing to see, and the risk depends on things that happen around you — a high temperature, a prescription, an anaesthetic. This guide covers what Brugada syndrome is, what makes it more dangerous, and what your medical ID should say.
What is Brugada syndrome?
According to healthdirect, Brugada syndrome is a rare genetic condition in which there is a problem with the electrical activity of the heart. This can cause arrhythmias (abnormal heart rhythms), and arrhythmias can cause sudden cardiac arrest.
You may have no symptoms at all. When symptoms do appear, healthdirect says they usually start around the ages of 30 to 50 and can include:
- heart palpitations
- feeling dizzy or lightheaded
- fainting
- cardiac arrest, if the heart suddenly stops beating
Symptoms often come on at night or when resting, not during exercise.
The triggers: fever, medicines, alcohol and drugs
healthdirect explains that some people with Brugada syndrome are more likely to have symptoms and arrhythmias with certain triggers:
| Trigger | What healthdirect advises |
|---|---|
| Fever | Treat any fever promptly, especially in children — a high body temperature increases the chance of complications. |
| Some medicines | Always check any new medicine with your doctor and pharmacist, including over-the-counter medicines and supplements. |
| Surgery and procedures | Mention your condition to your doctors before any surgery. |
| Alcohol and illicit drugs | Avoid them. |
Why this matters in an emergency
Fever is common when you are taken to hospital with an infection, and new medicines are given quickly. If the team does not know you have Brugada syndrome, the two most important precautions — bringing your temperature down and checking each drug — depend on you being able to tell them.
Brugada syndrome drugs to avoid: the list your doctors use
BrugadaDrugs.org is a non-profit reference developed by cardiologists at the University of Amsterdam’s Academic Medical Center with an international panel of Brugada syndrome experts. It sorts medicines into lists:
- Red — drugs that should be avoided by people with Brugada syndrome
- Orange — drugs that preferably should be avoided
- Green — drugs that may have an anti-arrhythmic effect
- Blue — drugs used to diagnose the Brugada ECG pattern
- Purple — a complete list of the drugs to avoid or preferably avoid, which the site provides for patients to give to all their health care providers
The site itself notes that much of the evidence comes from case reports, so decisions are made by your doctors weighing the risk. We have deliberately not reprinted the drug names here: lists are updated, and the safe choice is to point every clinician to the current list. Your medical ID can do exactly that — “Brugada syndrome: check brugadadrugs.org before prescribing” is short enough to sit at the top of your record.
When to go to hospital, and when to call 000
If someone with Brugada syndrome collapses
- If they lose consciousness and/or stop breathing normally, call Triple Zero (000) and ask for an ambulance.
- Start CPR as soon as possible, and send someone for a defibrillator.
- If a person with Brugada syndrome faints and then recovers, healthdirect says to seek urgent medical attention at the emergency department.
See our guides to how to do CPR and how to use a defibrillator.
How Brugada syndrome is diagnosed and treated
Diagnosis
healthdirect says Brugada syndrome is often diagnosed on an electrocardiogram (ECG) showing the characteristic “Brugada pattern”, sometimes picked up on a routine ECG when you have no symptoms. Other heart tests may be done, and a cardiologist may arrange a test in hospital where a specific medicine is given before an ECG to see whether it brings on the pattern. Genetic testing is also recommended.
Treatment
Treatment is decided by your cardiologist and may include avoiding triggers, treating fevers promptly, medicines to control the heart rhythm, a procedure called radiofrequency catheter ablation, or an implantable cardioverter defibrillator (ICD). An ICD monitors your heart rhythm and can deliver an electric shock to control a dangerous arrhythmia. If you have one, it belongs on your record — see what counts as a medical implant or device.
Is Brugada syndrome inherited?
Yes. healthdirect explains that Brugada syndrome is inherited from one of your parents, and that if you have the gene you have a 1 in 2 chance of passing it on to each of your children. If a family member is diagnosed, your doctor may recommend genetic testing, and seeing a genetic counsellor is a good idea if you are planning a pregnancy. A diagnosis often reaches several people in one family — including children, for whom fever is the trigger healthdirect singles out.
Who reads a Brugada syndrome medical ID
ANZCOR Guideline 2, which shapes first aid and resuscitation training in Australia, includes checking for “physical (eg. alert jewellery) or electronic alert devices (eg. smartphone application) that may be relevant to assessment or management”. For Brugada syndrome the readers are the paramedic at a collapse, the emergency doctor treating a fever, the anaesthetist before an operation, and the GP or pharmacist about to supply a new medicine.
What a Brugada syndrome medical ID should say
On the band
- BRUGADA SYNDROME
- TREAT FEVER PROMPTLY — CHECK ALL MEDICINES
- ICD, if you have one
- Your membership number, so the full record can be read
In the profile
- Your diagnosis, how it was found, and any genetic result.
- The instruction to treat fever promptly and to check new medicines against brugadadrugs.org.
- Your current medicines, and any medicine you have been told to avoid.
- ICD details: manufacturer, model and the clinic that checks it.
- Your cardiologist, GP and emergency contacts.
- Relatives who have been diagnosed or tested, if you want that shared.

Everyday steps that help
- Keep a thermometer and fever medicine at home, and ask your cardiologist what to do when you or your child has a fever.
- Tell your pharmacist about the diagnosis so it is on file, and check every over-the-counter product and supplement.
- Before any procedure, tell the surgeon and anaesthetist — healthdirect specifically advises mentioning the condition before surgery.
- Keep regular check-ups with your cardiologist.
- Make sure the people you live and work with know how to do CPR and where the nearest defibrillator is.
