Here's a summary of what was covered across the 10 conditions:
10 Common Heart Diseases with ECG Changes — Overview
  1. STEMI — Convex ST elevation in vascular territory, hyperacute T-waves, Q waves, reciprocal depression
  2. NSTEMI/Unstable Angina — ST depression, T-wave inversion, no Q waves; normal ECG possible
  3. Atrial Fibrillation — No P waves, fibrillatory baseline, irregularly irregular rhythm
  4. Complete (3rd degree) AV Block — Complete AV dissociation, independent slow escape rhythm
  5. Ventricular Tachycardia — Wide QRS ≥120 ms, AV dissociation, fusion/capture beats, concordance
  6. WPW Syndrome — Short PR (<120 ms), delta wave, widened QRS, pseudo-infarct Q waves
  7. Hypertrophic Cardiomyopathy — LVH voltage criteria, giant T-wave inversions (apical variant), abnormal Q waves
  8. Acute Pericarditis — Diffuse saddle-shaped ST elevation, PR depression, Spodick's sign; no Q waves
  9. Long QT / Torsades de Pointes — QTc ≥450 ms, T-wave alternans, R-on-T triggering polymorphic VT
  10. Pulmonary Embolism — Sinus tachycardia, S1Q3T3, T inversions V1–V4, RBBB pattern
Each condition includes annotated real ECG images sourced from peer-reviewed clinical literature. Let me know if you want deeper detail on any specific condition, management algorithms, or additional ECG examples.
