...these could easily be included in echocardiography software, which would allow automated generation of an LV mass-for-height z score and percentile for each child undergoing echocardiography.
LV mass was estimated by M-mode echocardiography in 440 healthy nonobese reference children (birth to 21 years) from Boston Children's Hospital.
