That's the complete ECG overview. Here's a quick navigation guide to what's covered:
What's included above:
- Basics - What an ECG measures, paper speed, calibration
- Waveforms - P, QRS, T, U waves; PR, ST, QT intervals with normal values (table)
- Heart rate calculation - From RR interval
- 12-lead system - All 6 limb + 6 precordial leads, regional groupings
- Systematic interpretation - 8-step approach
- QRS axis - Normal range, LAD/RAD causes, quick estimation method
- Conduction abnormalities - AV blocks (1st, 2nd Mobitz I/II, 3rd-degree), BBB (RBBB, LBBB), fascicular blocks
- Hypertrophy - LVH and RVH criteria
- Ischemia/MI - Hyperacute T waves, STEMI, Q waves; localization table (anterior, lateral, inferior, posterior)
- Arrhythmias - AFib, flutter, VT, VF, Torsades, PVCs
- WPW / Pre-excitation - Delta wave, short PR
- Electrolyte effects - Hyperkalemia, hypokalemia, hypercalcemia, hypothermia
- Long QT - Acquired vs congenital, risk thresholds
- Special situations - Athletes, COVID-19
- Automated/AI interpretation - Capabilities and limitations
Let me know if you want to go deeper on any specific area - arrhythmia algorithms, STEMI mimics, drug-induced QT prolongation, or anything else.
