Brugada ECG Patterns: A Comprehensive, Clinically Oriented Guide Overview Brugada syndrome is an inherited cardiac ion-channel disorder characterized by distinctive ECG patterns in the right precordial leads and an increased risk of malignant ventricular arrhythmias and sudden cardiac death (SCD), often in structurally normal hearts. The ECG phenotype is dynamic and may be concealed, unmasked, or modulated by fever, drugs, and autonomic tone. --- ECG Patterns of Brugada Syndrome Type 1 (Diagnostic Pattern) Key features Coved ST-segment elevation ≥2 mm in ≥1 right precordial lead (V1–V3) Followed by a negative T wave J-point elevation with downsloping ST segment Clinical significance Only ECG pattern diagnostic of Brugada syndrome (when present spontaneously or induced by sodium-channel blocker) High arrhythmic risk, especially if spontaneous and associated with symptoms --- Type 2 (Suggestive Pattern) Key features Saddleback ST elevation ≥2 mm ST segment remains elevated ≥1 mm Po...
