Abstract Objective: To investigate the measurements of echocardiography in healthy children. Methods: One thousand three hundred and forty-four healthy children were divided into ten groups by age. Parameters including dimension of cardiac chambers and great vessels, left ventricular function and flow velocity through different valves were measured with HP/Sonos2500, HP/Sonos5500 or Philips/Sonos7500 ultrasound diagnostic systems. The data was analyzed by SPSS 11.0 software. Data were expressed as x±s. The Pearson correlation analysis was performed to determine the correlation between all measurements and age. Results: No correlations were observed between MVE, MVE/MVA, PAV, △D% and age. MVA, TVA, HR, FS, EF were inversely correlated with age. Other measurements including AOD, LAD, LVDd, LVDs, MPA, IVS, LVPWd, LVPWs, SV, CO, LVEDV, LVESV, TVE, TVE/TVA and AOV correlated positively with age. The measurements of cardiac and great vessels were significantly different between boys and girls above three-year-old children. The measurements of girls were slightly lower than those of boys. However, no differences were found in parameters of left ventricular function such as FS and EF between boys and girls. Conclusion: Measurements of echocardiography change in different age of children. But it should be noted that some parameters may not be affected by age.
