ECG Features
- Pathological Q waves (must be ≥30 ms wide and ≥0.1 mV deep in amplitude or QS complex) in anterolateral leads (V2-V6, I, aVL)
- Evidence of acute or evolving myocardial injury (i.e. ST-elevation in two contiguous leads ≥2 mm in men or ≥1.5 mm in women in V2-V3 and/or ≥1 mm in V4-V6, I, and aVL)
- Note: Only use this diagnosis when both (1) pathological Q waves and (2) ST-elevation are present. If only ST-elevation is present (without pathological Q waves), ST and/or T wave abnormalities suggesting myocardial injury should be used instead.
