LVH

Question 1

🫀 LVH (Left Ventricular Hypertrophy)

✅ Voltage Criteria

Answer 1

Limb leads:
* R in I + S in III > 25 mm
* R in aVL > 11 mm
* R in aVF > 20 mm
* S in aVR > 14 mm

Precordial leads:
* R in V4/V5/V6 > 26 mm
* R in V5/V6 + S in V1 > 35 mm
* Largest R + Largest S > 45 mm

Question 2

✅ Non-voltage Criteria:

Answer 2

• LV strain pattern in L-sided leads (ST ↓, T wave ↓/inversion)
  
  • ↑ R wave peak time > 50 msec in V5/V6 ⭐
• LA enlargement and LAD
