Overview
Classification
- Type 1 ST segment elevation is diagnostic of Brugada syndrome and is characterized by a coved ST-segment elevation ≥2 mm (0.2 mV) followed by a negative T wave.
- Type 2 ST-segment elevation has a saddleback appearance with a high take-off ST-segment elevation of ≥2 mm followed by a trough displaying ≥1 mm ST elevation followed by either a positive or biphasic T wave.
- Type 3 ST-segment elevation has either a saddleback or coved appearance with an ST-segment elevation of <1 mm.
