Physical examination on heart-lung perfusion and ventilation of patient with heart disease was performed by radioisotopes and the results were discussed clinically.
The perfusion of upper lungs in P. A. system in the case of heart diseases increased more definitely than that of no heart disease. But few changes of ventilation were observed on upper lungs in the case of heart diseases.
For this reason, the ventilation-perfusion ratio of heart diseases were lower than that of normals.
T/F differs distinctiy from ASD on angiograph which was done by 99mTc.
In a case of T/F, appearance of the radioisotope on lungs was not sooner than on Aorta.
In a case of ASD, on the other hand, the radioisotope was found systematically in vena cava, right heart, pulmonal artery, lungs, and left heart in order of the appearance.
