CLINICAL INSIGHT

When to Use

When to Use

  • ECG screening for left ventricular hypertrophy
  • Chronic hypertension monitoring
  • Sex-specific assessment (more sensitive in females)
  • Complements Sokolow-Lyon and other LVH criteria
  • Higher specificity than Sokolow-Lyon, particularly in women

Formula

CLINICAL INSIGHT

Practical Pearls

Technical Notes

  • Measure in smallest boxes (0.5 mm divisions)
  • Large amplitudes may indicate athletic conditioning (normal)
  • Poor R wave progression can interfere with measurements
  • Cornell criteria more specific in women than Sokolow-Lyon
  • Should be interpreted in clinical context (HTN, symptoms)

Comparison with Other Criteria

  • Sokolow-Lyon: SV1 + RV5/6 ≥ 35 mm (higher sensitivity, lower specificity)
  • Cornell: Better specificity, particularly useful in women
  • Neither criterion reliably excludes LVH; echo remains gold standard

Cornell Voltage Criteria

The Cornell Voltage Criteria is one of the most accurate EKG methods for diagnosing Left Ventricular Hypertrophy (LVH). It accounts for gender-based differences in myocardial mass, using a sum of R in aVL and S in V3. Thresholds: Men > 28 mm, Women > 20 mm.
