Ponderal index was associated with QRS voltage criteria; leaves open whether body build adjustment improves LVH diagnostic accuracy.
Does body build (ponderal index) affect QRS voltage on the electrocardiogram in normal men?
Adjusting QRS voltage criteria for body build (ponderal index) may improve the accuracy and specificity of electrocardiographic diagnosis of early left ventricular hypertrophy.
KILTY et al. (1965) studied this question.
