Overview

The findings of Brugada syndrome are often concealed, but can be unmasked or modulated by a number of drugs and pathophysiological states including:

• Sodium channel blockers
• Fever
• Vagotonic agents that mimic sleep
• Tricyclic antidepressants
• Cocaine
• Propranolol intoxication

Risk Statification

• Patients with syncope and an abnormal Type 1 ECG are at higher risk
• Asymptomatic patients at risk can be identified
  • Presence of spontaneous Type 1 ST-segment elevation
  • Characteristics of the S wave
  • Presence of late potentials
  • Inducibility of VT/VF using PES.
