<aside>

2 Criteria (either/or)

• avL: R > 11 mm
• V5/V6 (R) + V1 (S) > 35 mm </aside>

Signs

• LAD: II -, I+

  

• Bigger amplitude of QRS

  • More positive in Left leads
  • More negative in right leads (V1, III)
  • Dx → If you meet any criteria
  • More criteria = more likely
    • aVL: R > 11 mm
    • I(R) + III(S) > 25 mm
    • I: R > 11 mm
    • V5/V6: R: > 26 mm
    • V5/V6 (R) + V1 (S) > 35 mm
    • Largest R + Largest S > 45 mm

• *Strain (severe hypertrophy leading to ischemia) may lead to ST Depression
