Using the ballistcardiograph of Starr's type with two i. e. head-foot and left-right directions, the cardio-vascular dynamical analysis was performed. At the same time Wezler's and Blumberger-Holldack's method were also applied under the control of Fick-Cournand's method and electrokymography. 1. The stroke volumes calculated by Starr's method Vs (Bcg) were compared with those measured by Wezler's Vs (w) in 50 normal and 74 hypertensive cases. So far as the absolute values were concerned, except for the cases with high output load beyond a certain extent, it may be safe to say that both Vs (1Q) obtained by means of substituting A in Starr's formulae for the aortic cross section Q in Wezler's formula and Vs (3) calculated by means of Tanner's formula tend to approximate to Vs (W). The tendency of the same sorts can be also seen about the mean values. The investigation upon the difference between Vs (1Q) and Vs (3) reveals that such a difference is more marked in the "Entspannungstypus (Duesberg, Schroeder)" of normal health and in the "Minutenvolumentypus" of arterial hypertension. With respect to the age, the difference between Vs (1Q) and Vs (3) is relatively greater in youth, whereas is less above middle-age. These facts suggest that there is possibility of room for further study, therefore these facts demand a due deliberation in the clinical application of the ballistcardiography. 2. About the time-relation on the ballistcardiogram and the cardio-dynamical values obtained by Blumberger-Holldack's method, in addition to the cases just described, 14 cases with Msi, 3 cases with Ai, and 4 cases with auricular fibrillation were examined. Generally speaking the modes of the variations of QH and QI show the similar tendency with those of the variations of the "Anspannungszeit (ASZ)". The " ASZ" is more relative, to QI than QH. Some factors in addition to "cardiac recoil" are possible to participate in H wave, and on the other hand any factor besides "aortic impact" appear to take not so much in I wave. The origin of L wave must be very complex. Finally some considerations were made upon the significance of the main diastolic waves with special reference to the problem upon the high output load.
