BACKGROUND In older children, one of the standards for indexing left ventricular mass (LVM) is height raised to an exponential power of 2.7. The purpose of this study was to establish a normal value for the pediatric age group and to determine how, if at all, LVM/height(2.7) varies in children. METHODS M-mode echocardiography was performed in 2,273(More)
