Early warning of an evolving STEMI.
History and findings suggestive of acute coronary syndrome.
Key 12-Lead Features
- J-Point depression with up-sloping ST segments.
- Tall, prominent, symmetric T waves in the precordial leads.
- Upsloping ST segment depression > 1mm at the J-point in the precordial leads.
- Absence of ST elevation in the precordial leads.
- ST segment elevation (0.5mm-1mm) in aVR.
- “Normal” STEMI morphology may precede or follow the DeWinter pattern.
Key Treatment Points
- Patient advocacy for a cardiology consult
- Monitor for potential emerging STEMI
