Cornell Voltage Criteria
voltage sum =
= (S in V3 in mV) + (R in aVL in mV)
where:
• 1 mm = 0.1 mV
Interpretation:
• LVH is present in a male if sum > 2.8 mV
• LVH is present in a female if sum > 2.0 mV
Multiple Logistic Regression Equation:
Patients with Normal Sinus Rhythm
exponent =
= 4.558 - (0.092 * ((R in aVL in mm) + (S in V3 in mm)) - (0.306 * (T in V1 in mm)) - (0.212 * (QRS duration in hundredths of a second)) - (0.278 * (P terminal force in V1 in mm*sec)) - (0.559 * (sex value))
where
• sex value = 1 if male, 2 if female
• QRS duration in hundredths of a second = ((QRS duration in seconds) * 100)
• P terminal force is the area of the terminal negative deflection of the P wave
Interpretation
• LVH present if exponent < -1.55
Multiple Logistic Regression Equation:
Patients with Atrial Fibrillation
exponent =
= 5.045 - (0.093 * ((R in aVL in mm) + (S in V3 in mm)) - (0.312 * (T in V1 in mm)) - (0.325 * (QRS duration in hundredths of a second)) - (0.602 * (sex value))
where:
• sex value = 1 if male, 2 if female
Interpretation:
• LVH present if exponent < -1.20
