Abstract
Left ventricular end-diastolic dimension (LVD) in the echocardiogram (E) is widely used to assess the LV size. There is no study available where difference in male (M) and female (F) growing children were examined. Therefore, we studied 110 M and 90 F normal school children, 5-14 years of age and with body surface area (BSA) varying from 0.7 to 1.59. Strip chart E recordings of the LV at its midcavity sector containing mitral echos were obtained by means of a 2.25 M Hz transducer in the standard fashion. Internal LVD was measured in millimeters at the onset of the Q wave of the EKG for several cardiac cycles and averaged. Our results for the mean and 1 standard deviation in M and F children with the different BSA were as follows:
This study shows increase in LVD with larger BSA as in other studies in both M and F children. However, there was no statistically significant difference in LVD between M and F growing children at any BSA.
