Brugada Syndrome: Clinical Guide 📉 ECG Diagnosis (V1-V2, 2nd-4th ICS) • Type 1 (Diagnostic): ≥2mm coved ST elevation → downsloping segment → inverted T-wave. May be unmasked by fever or sodium channel blockers. • Type 2/3 (Non-Diagnostic): Saddleback ST elevation. Requires clinical correlation. • Hallmark: Pseudo-RBBB pattern without true conduction delay. ⚠️ Risk Stratification (2022 ESC Guidelines) ICD Recommended: • Secondary Prevention: After aborted SCA or sustained VT/VF. • High-Risk Prim
