Syncope in a Patient with Brugada Pattern
A 45-year-old man presents with two episodes of syncope in the past month, both occurring at rest while sitting. He has no prior cardiac history. His father died suddenly at age 50. Physical exam is unremarkable. ECG shows a type 1 Brugada pattern (coved ST elevation ≥2 mm in V1–V2 followed by negative T wave) in the right precordial leads. He is currently asymptomatic in the emergency department. His vital signs are stable. The emergency physician asks whether he needs immediate cardiology consultation or can be discharged with outpatient follow-up.
1. What is the most appropriate immediate management for this patient, and why?
Read the worked answer
This patient has syncope and a spontaneous type 1 Brugada ECG pattern, which places him at high risk for sudden cardiac death. He requires immediate cardiology/electrophysiology consultation and hospital admission for continuous cardiac monitoring. The syncope is likely arrhythmic (ventricular fibrillation) given the ECG pattern and family history. He should not be discharged. Further evaluation includes ruling out reversible causes (e.g., fever, electrolyte imbalance, drugs), and consideration of an implantable cardioverter-defibrillator (ICD) because of the high-risk features (syncope + spontaneous type 1 pattern).
2. What additional diagnostic testing would you order, and what are the key safety considerations?
Read the worked answer
Order: (1) continuous telemetry; (2) echocardiogram to rule out structural heart disease; (3) careful review of all medications for Brugada-precipitating agents (e.g., sodium channel blockers, certain antidepressants, antipsychotics); (4) electrolyte panel including potassium and magnesium; (5) consider an electrophysiology study (EPS) if diagnosis remains uncertain, though its role is debated; (6) genetic testing and family screening. Safety: Avoid provocation with ajmaline/flecainide in the emergency department unless done under controlled conditions by experienced staff. Educate the patient to avoid triggers (fever, large meals, alcohol, certain drugs) and to seek immediate care for presyncope. Fever should be treated aggressively with antipyretics. The patient should be given a list of drugs to avoid.
