Brugada Syndrome: ECG Pattern Review 🫀 Recognize the Three ECG Types (V1–V3, 2nd/3rd ICS): 🔹 Type 1 (Coved, Diagnostic): - J wave elevation ≥2 mm - Negative T wave - Coved, gradually descending ST segment - Diagnostic for Brugada syndrome 🔹 Type 2 (Saddleback, Non-diagnostic): - J wave elevation ≥2 mm - Positive or biphasic T wave - Saddleback ST segment (≥1 mm elevation) - May convert to Type 1 with Na⁺ channel blocker 🔹 Type 3 (Saddleback, Non-diagnostic): - J wave elevation ≥2 mm - Saddle

Brugada Syndrome: Quick Clinical Guide ECG Patterns (V1–V2, 2nd/3rd ICS) 📉 🔹 Type 1 (Diagnostic): ≥2 mm coved ST elevation, downsloping ST segment, inverted T-wave. 🔹 Type 2: ≥2 mm saddleback ST elevation, upright/biphasic T-wave. 🔹 Dynamic changes: Fever/ajmaline can unmask Type 1. 🔹 Pseudo-RBBB (no true conduction delay). --- Diagnosis: Shanghai Score 2020 📋 ✅ Score ≥3.5 confirms BrS: - 3.5: Spontaneous/drug-induced Type 1 ECG. - 2: Family SCD
