1. The measured values in various parts of the heart in fluorograms, examining how they change in ten years, was calculated. Its result showed the difference of the increse caused by body-weight was hardly noticed. 2. Concerning the relation between body-weight and the measured value of heart; in the group of fat people, the left aortic arch diameters and the transverse diameters right and left showed a considerable greater value than in those of average and thin people. 3. with recept to the transition of blood pressure and cardiac measurements over ten years, the high blood pressure group showed a notable increase in the aortic arch diameters right and left and the left transverse diamters against the normal blood pressre group. 4. As to relation between blood pressure and cardiac measurements, the high blood pressure group showed high value in the left transverse diameters and the aortic arch diameters right and left, in comparison with the normal blood pressure group.
