Abstract
|
|
|
Cardiac measurement by Roentgenological method was carried out on 140 Korean preschool age i ch; ;dren, 7n males and 63 females.
Formulae used in this study are as follows.
Predicted heart volume=K x Broad diameter of the heart x Long diameter of the heart x Depth diameter.
Relative heart volume=Predicted heart volume/Body surface area
The constant K represents the product of an ellipsoid area factor and a correction factor for f magnification of the cardiac image.
Body surface area was obtained by Du Bois nomogram.
Mean±standard deviation of the cardiac volume in various age, height and weight are as shown
Tables 4,7 and 10.
The results obtained from this study are as follows;
(1) Predicted heart volume increases proportionally to the age, height and weight of children.
(2) Relative heart volume shows no correlation the age, height or weight of the children.
(3) In comparison with Mannheimers data, relative heart volume of? the Korean preschool children
are smaller than American preschool children.
(4) Reontgenological mensuration is simple and reliable method in determining the cardiac volume.
