The guide covers all 10 diseases with clinical ECG images sourced from peer-reviewed medical literature. Here's a recap of what was covered:
- STEMI — Convex ST elevation localized to coronary territory + reciprocal changes
- Atrial Fibrillation — No P waves + irregularly irregular rhythm
- Ventricular Tachycardia — Wide QRS tachycardia + AV dissociation
- Complete Heart Block — AV dissociation with independent atrial/ventricular rhythms
- WPW Syndrome — Short PR + delta wave + widened QRS triad
- Acute Pericarditis — Diffuse saddle-shaped ST elevation + PR depression (vs STEMI key differentiator)
- Pulmonary Embolism — Sinus tachycardia + S1Q3T3 + right ventricular strain pattern
- LVH — High voltage + lateral strain pattern (ST depression + T inversion)
- Hypertrophic CMP — Giant T-wave inversions + deep lateral Q waves
- Brugada Syndrome — Coved ST elevation ≥2 mm in V1–V2 with inverted T wave
Each section includes the specific waveform changes, lead localization, and clinical significance to help distinguish one condition from another on a 12-lead ECG.
