Here's a quick recap of what was covered:

The 10 common heart diseases with ECG changes are:
  1. STEMI - Hyperacute T-waves, ST elevation in a coronary territory, reciprocal depression, Q waves
  2. Atrial Fibrillation - Absent P waves, irregularly irregular QRS
  3. Atrial Flutter - Sawtooth flutter waves at ~300/min, 2:1 or 3:1 ventricular response
  4. Complete Heart Block - Full P-QRS dissociation, slow escape rhythm
  5. Left Bundle Branch Block (LBBB) - Wide QRS, M-shaped R in lateral leads, rS in V1
  6. Right Bundle Branch Block (RBBB) - Wide QRS, RSR' ("rabbit ears") in V1, broad S in I/V6
  7. Left Ventricular Hypertrophy (LVH) - Tall voltage, left axis, lateral strain pattern
  8. Wolff-Parkinson-White (WPW) - Short PR, delta wave, wide QRS
  9. Hypertrophic Cardiomyopathy (HCM) - LVH voltage, septal Q waves, giant T-wave inversions
  10. Acute Pericarditis - Diffuse concave ST elevation, PR depression, no Q waves
Three ECG images are embedded in the answer above - a detailed STEMI pattern chart (Wellens/De Winter/posterior OMI), a real 12-lead anterior-lateral STEMI example, and a classic HCM ECG with deep T-wave inversions. All descriptions are sourced from Braunwald's Heart Disease, Tintinalli's Emergency Medicine, Goldman-Cecil Medicine, and validated ECG libraries (LITFL, ECGwaves).
