Treatment

Brugada syndrome treatment depends on your risk of a serious abnormal heartbeat.

You're considered at high risk if you have:

• A personal history of serious heart rhythm problems
• Fainting spells
• Survived sudden cardiac arrest

If you don't have any symptoms, you may not need any specific treatment because your risk is likely low. However, your doctor will recommend the following steps to reduce your chances of an abnormal heart rhythm.

• Treat a fever aggressively. Fever is a known trigger of abnormal heartbeats in people with Brugada syndrome, so use fever-reducing medications at the first sign of a fever.
• Avoiding drugs that may trigger an abnormal heart rhythm. Many drugs can increase the risk of an irregular heartbeat, including certain heart medications and antidepressants. Too much alcohol can also increase your risk. Always tell your doctor about the medications you take, including drugs and supplements bought without a prescription.
• Avoiding playing competitive sports. If you're at high risk of a serious irregular heart rhythm, your doctor may tell you not to play competitive sports.

Surgery or other procedures

If you've had cardiac arrest or a worrisome fainting episode, the main treatment is an implantable cardioverter-defibrillator (ICD).

• Implantable cardioverter-defibrillator (ICD). This small, battery-operated device is placed in your chest to continuously monitor your heart rhythm and delivers electrical shocks when needed to control abnormal heartbeats. ICD placement usually requires an overnight hospital stay. ICDs may cause unnecessary shocks when they're not needed, so it's important to discuss the benefits and risks with your doctor.
• Drug therapy. Sometimes, medications such as quinidine are used to prevent a potentially dangerous heart rhythm. This drug may be given along with an ICD.
• Catheter ablation. If an ICD doesn't effectively and safely control your Brugada syndrome symptoms, a procedure called radiofrequency catheter ablation may be an option. A long, flexible tube (catheter) is inserted through a blood vessel and threaded to your heart. The catheter delivers high energy that scars or destroys the heart tissue responsible for the abnormal heart rhythm.

If you have Brugada syndrome, it's important to schedule regular visits with your doctor to make sure you're properly managing your heart condition. Regular checkups can help your doctor decide if you need to change your treatment and may help catch any new problems early.
