Abstract

Cardiac structures were measured in 98 dogs to obtain the normal structure values of the heart. There was no difference in the measured values between male and female dogs. Puppies had a significantly higher heart-body weight ratio (12.6±6.33 g/kg) than the adult dogs. There were no significant age differences, however, in any other measured value. Such value was independent of sex, age and body weight. There was a tendency that the circumference of the left cardiac valves was shorter than that of the right (Pa>Ao, Tri>Mi).
The left and right ventricular wall increased in thickness at almost the same speed, because there were no significant changes in the right ventricle and the ventricular septum ratio (RV/IVS) (0.50±0.12-0.67±0.16) or the ventricular septum and the left ventricular ratio (IVS/LV) (0.88±0.09-1.33±0.18).
