Parameters:
(1) Cornell voltage product in mV•ms
(2) age in years
(3) body mass index (BMI) in kilograms per square meters
(4) gender
adjusted Cornell voltage product in mV•ms for males =
= ((Cornell volt product in mV•ms) + (1.8289 * (age)) + (19.0417 * (BMI)) - 360) / 2 =
= (0.5 * (Cornell voltage product)) + (0.9144 * (age)) + (9.5208 * (BMI)) - 180
adjusted Cornell voltage product in mV•ms for females =
= ((Cornell voltage product in mV•ms) + (3.2963 * (age)) + (18.1142* (BMI)) - 420) / 3 =
= (0.333 * (Cornell voltage product in mV•ms)) + (1.0988 * (age)) + (6.038 * (BMI)) - 140
where:
• The authors report the voltage product in mV•ms. The correct units may be mm•ms.
Performance (Table 6, Norman and Levy):
• An adjusted voltage product 1,572 mV•ms was 50% sensitive for detecting left ventricular hypertrophy.
• An adjusted voltage product 1,325 mV•ms was 85% specific for detecting left ventricular hypertrophy. An adjusted product 1,559 mV•ms was 95% specific.
