Relationship between cardiac parameters and cube root of BSA corrected by subcutaneous fat weight.

Left ventricular internal dimension (LVIDd), aortic root dimension (AOD) and left atrial dimension (LAD) were measured echocardiographically in 688 normal children, ranging in age from 5 to 15. Lean body surface area (BSA) was calculated from height and lean body weight which was estimated from triceps skin fold thickness, upper arm circumference and body weight. Cardiac parameters (LVIDd, AOD, LAD) were well correlated with 3 square root BSA or 3 square root lean BSA (r = 0.72 approximately 0.89). Regression lines of LVIDd and AOD against 3 square root BSA or 3 square root lean BSA were compared between boys and girls. Statistically significant sex difference was observed in regression lines of LVIDd and AOD plotted against BSA (p less than 0.005), but this difference disappeared when plotted against lean BSA. It is concluded that the sex difference of LVIDd and AOD corresponding to a similar BSA depended on the difference of lean body weight between boys and girls.

Relationship between left ventricular muscle volume and body surface area corrected by subcutaneous fat weight in normal children.

Left ventricular muscle volume (LVMV) was measured echocardiographically in 688 normal children ranging in age from 5 to 15. Lean body surface area (BSA) was obtained from height and lean body weight, which was estimated using triceps skinfold thickness, upper arm circumference and body weight. Regression lines of LVMV against BSA or lean-BSA were compared between boys and girls. There was statistically significant sex difference in regression lines when LVMV were plotted against BSA (p less than 0.005), but this difference disappeared when plotted against lean-BSA. We conclude that the sex difference of LVMV with a similar BSA originates from the difference of lean body weight between boys and girls.

Clinical estimation of left ventricular size: precordial electrocardiographic voltage corrected by the measurement of thorax.

The left ventricular muscle volume (LVMV) was determined echocardiographically and the radius of the circle with equal circumference to the thorax (R1) was calculated from thorax-circumference in 688 children as a part of the Shimane Heart Study. correlation of the summed precordial voltage (SV1 + RV5) with LVMV was not close (r = 0.377 in boys and -0.095 in girls). The precordial voltage (SV1 + RV5) was corrected by the square of R1 to compensate for the diminution of electrical potential by distance. Correlation between (R1) 2 x (SV1 + RV5) and LVMV was good in boys (r = 0.681) and relatively good in girls (r= 0.554). This fact indicates that LVMV can be predicted from ECG and anthropometric measurements of thorax without using echocardiography. Therefore, (R1) 2 x (SV1 + RV5) seems to have clinical applicability as the index of LV size, if the differences in (R1) 2 x (SV1 + RV5) and in the correlation coefficient between both sexes are clarified further.
