2/ What do you see on ECG to identify extreme axis deviation?
Negative deflection in lead I + negative deflection in aVF = extreme axis deviation
Negative deflection in lead I + negative deflection in aVF = extreme axis deviation
3/ What about the precordial leads?
Do you notice dominant R waves, S waves, or T-wave inversions?

4/ Putting it together, what do these ECG findings suggest?
If you thought of RV hypertrophy, you’re right!

5/ Why do we see this electrical pattern on ECG?
Vector of ventricular depolarization with hypertrophied RV is moving towards leads V1 and V2 (+deflection) and away from V4-V6 ( - deflection)
