Impedance cardiography in normal children

Cardiac output, cardiac index (cardiac output/body surface) and stroke volume were investigated in 20 normal children by means of impedance cardiography. Significant differences were found in the mean values of cardiac output and cardiac index between both sexes, as well as in means of cardiac index between younger and older children. The obtained data generally agreed with the results of other investigators performing the examination by using the same technique and other methods.
