ECG LVH Voltage Criteria (Sokolow-Lyon, Cornell)
ECG voltage criteria for left ventricular hypertrophy: Sokolow-Lyon (SV1 + max RV5/RV6), Cornell (SV3 + RaVL) and Peguero-Lo Presti (deepest S + SV4).

Example
- S wave in V1
- 20 mm
- R wave in V5
- 18 mm
- R wave in V6
- 16 mm
- S wave in V3
- 12 mm
- R wave in aVL
- 10 mm
- Sex
- Male (Cornell > 28 mm)
Result: Sokolow-Lyon 38 mm positive (>= 35 mm); Cornell voltage 22 mm.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Sokolow-Lyon
- SV1 + max(RV5, RV6) >= 35 mm is positive.
- Cornell voltage
- SV3 + RaVL > 28 mm (men) or > 20 mm (women) is positive.
- Peguero-Lo Presti
- Deepest S wave in any lead + SV4 >= 28 mm (men) or >= 23 mm (women) is positive (2.8 and 2.3 mV).
- Caveat
- Voltage criteria are specific but not sensitive; a negative ECG does not exclude LVH and echocardiography is the reference standard.
What you enter
- S wave in V1
- R wave in V5 (RV5 or RV6; the criterion uses the larger)
- R wave in V6 (RV5 or RV6; the criterion uses the larger)
- S wave in V3
- R wave in aVL
- Deepest S wave in any lead (for Peguero-Lo Presti)
- S wave in V4 (for Peguero-Lo Presti)
- Sex (for the Cornell threshold)
