Brugada Syndrome 1 C4551804
A genetic heart condition causing abnormal heart rhythms that can lead to fainting or sudden cardiac arrest, especially during sleep. It requires careful monitoring and may need a pacemaker or defibrillator.

Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Disease management and monitoring
Active treatment with regular monitoring by a healthcare provider is recommended.
Implantable cardioverter-defibrillator (ICD)
ICD implantation is the primary intervention for high-risk Brugada syndrome patients to prevent sudden cardiac death. The device continuously monitors heart rhythm and delivers appropriate shocks when life-threatening arrhythmias are detected.
Fever management and trigger avoidance
Prompt fever reduction is critical as febrile states can unmask or exacerbate Brugada syndrome. Patients should avoid known triggers including certain medications, extreme temperatures, and excessive alcohol consumption.
Additional treatment options
Antiarrhythmic medication therapy
Quinidine or other antiarrhythmic agents may be prescribed to reduce arrhythmia burden in selected patients. Medication management requires careful monitoring for efficacy and potential side effects.
medicationCatheter ablation
Radiofrequency catheter ablation targets the abnormal electrical pathways in the right ventricular outflow tract. This procedure is considered for patients with frequent arrhythmic events or ICD storms who prefer to reduce device therapy.
procedureRegular cardiac monitoring and follow-up
Scheduled electrocardiographic monitoring and clinical evaluations help assess disease progression and treatment effectiveness. Remote monitoring of ICD devices allows early detection of arrhythmias.
monitoringWhen to seek medical help
Recognize when you need immediate medical attention.
See a doctor within 24 hours
Moderate to severe symptoms that may indicate worsening of this condition. Prompt medical evaluation is recommended.
Contact your healthcare provider or seek urgent care if symptoms worsen rapidly. Go to the emergency department for life-threatening symptoms.
