De Winter T Waves Explained | The Hidden STEMI Equivalent on ECG

Learn about De Winter T waves, a crucial ECG finding that can be a STEMI equivalent, indicating a proximal LAD occlusion and potential anterior wall myocardial infarction. In this ECG tutorial, we'll explore the characteristics of De Winter T waves, including upsloping ST depression and tall T waves, and how to identify them on an ECG. Understanding De Winter T waves is essential for medical professionals in the ICU, emergency medicine, and internal medicine, as it can help diagnose acute coronary syndrome, including STEMI and non-STEMI. Our medical animation and ECG identification practice will help you improve your clinical skills and ECG interpretation, enabling you to provide better care for patients with chest pain and potential heart attack. By mastering the art of ECG interpretation, you'll be able to recognize the subtle signs of De Winter T waves and take prompt action to save lives. Whether you're an experienced cardiologist or just starting your career in cardiology education, this video will provide you with valuable insights and practical knowledge to enhance your ECG skills and stay up-to-date with the latest in emergency ECG and critical care ECG. #ekg #DeWinterTWaves #stemi #Cardiology #EmergencyMedicine #MedicalEducation

👉 What you’ll learn in this video:

What the LAD artery does and why a blockage is called the “widowmaker”
How ST elevation develops in a classic STEMI (transmural infarct)
Why De Winter T waves show up instead of ST elevation

Key ECG features:
upsloping ST depression, tall symmetric T waves, and aVR changes
Real patient case: chest pain, no ST elevation, but classic De Winter pattern
Why De Winter = STEMI equivalent → needs urgent cath lab activation

⚡ ECG Key Takeaway:

De Winter T waves = STEMI equivalent
No ST elevation does not mean no STEMI
Always recognize this pattern to avoid missing a proximal LAD infarction
