Here's a summary of everything covered:
What You Got
ECG Basics (with pictures from Harrison's & medical literature):
- Cardiac conduction system — SA → AV → His → Purkinje, with labeled heart diagram
- ECG waveforms — P wave, QRS complex, T wave, U wave — what each represents physiologically
- Intervals & segments — PR, QRS, QT, ST with normal values and clinical meaning
- ECG paper — the 0.04s/0.20s grid rules, heart rate calculation (300 rule + table)
- 12-lead ECG — electrode placement photo, which leads view which territory, coronary artery correlation
- Normal sinus rhythm — full 12-lead example with criteria checklist
- Systematic 7-step reading method — use this every single time
28-Day Learning Schedule:
- Week 1 — Foundation (waves, intervals, normal sinus rhythm)
- Week 2 — The 12 leads (axis, territory, R-wave progression)
- Week 3 — Arrhythmias & conduction blocks (AF, heart block, BBB, VT)
- Week 4 — Clinical pathology (STEMI, ischemia, LVH, electrolytes, pericarditis)
Since today is Saturday, you start on Day 1 right now — cardiac anatomy and the conduction system. Good timing!
