    Abstract:
    During the treatment of cardiacs with the diastolic counterimpulse, or during the diastolic counterimpulse experimentation among animals (6 dogs), we calculated the cardiac flux. At the clinic, by comparison with the cardiac flux obtained by the conventional method, the cardiac flux obtained by the intra-aortic differential pulse pressure contour method showed the correlation coefficient r = 0.83 through 20-time calculations (n) and the regression equation Y = 0.385X + 1.99. During the experimentation among animals, by comparison with the cardiac flux by means of the electromagnetic meter, this method showed the correlation coefficient r = 0.77, n = 21 and the regression equation Y = 0.586X + 0.579. If we note the coefficient between the cardiac flux at the abnormally - high value and the diastolic increase wave form, we found an inverse correlation. That is to say, the higher cardiac flux is parallel to the narrowness of the wave form. As shown above, this method would seem reliable, but it is most important to establish clearly the condition; and at the moment, for the cardiac flux of more than 7.0, it would be necessary to analyse the diastolic wave form. The study on the peripheral vessels and the venous system is quite important with the necessity of a knowledge on the differential pulse pressure contour method.
