Each section above includes a real 12-lead ECG from the medical literature with annotated findings. Here's a brief orientation to use this guide effectively:
How to read each ECG image: Every image is drawn from peer-reviewed clinical/educational sources and is described in detail — look for the specific features called out in the ECG changes section above each image (e.g., the slurred delta wave in WPW, the saddle-shaped ST in pericarditis, the RSR' pattern in RBBB).
Key differentials to keep in mind:
- Wide QRS tachycardia → always assume VT until proven otherwise
- Diffuse ST elevation → pericarditis (saddle shape + PR depression) vs. STEMI (convex, territory-specific)
- Short PR + wide QRS → WPW vs. LBBB (no delta wave in LBBB)
- Irregular rhythm → AF (no P waves) vs. multiple PACs/PVCs (P waves present but abnormal)
