Some modifications upon Wezler's new method which is published in 1949 were made by us, as follows;1. To registrate the pulse wave a beryllium membrane was applied and the mechanical movement was amplified electrically.2. Xray-kymographically the cross section of aorta was estimated and corrected by the height of blood pressure level.3. The correlation between manschette pressure and intraarterial pressure which are put into Broemser-Ranke's formula was examined closely.There are taken place the comparative studies upon both Wezler-Böger's and Fick-Cournand's method.i) According to W-B's method, in 20 healthy men there were determined M. V., W and E'; on average, 6.04±1.22l/min., 1327±231dyne cm-5 and 1640±295dyne cm-5 respectively.ii) M. V. of 16 patients with bronchial asthma is almost within normal range, while E' is somewhat increased.iii) 128 cases suffering from essential hypertension were classified, under consideration of years, according to both W-B's and K-W's methods.iv) 7 of 10 patients with congestive heart failure showed subnormal M. V., augmented W and E', while in 3 among them there could be found changes with reversal direction.v) Hemodynamical values during each cardiac cycle in arrhythmia were determined; typical case records were explained.vi) In 23 cases M. V. determined by W-B's method is on average by 0.2l/min higher than that estimated by F-C's.vii) Before and after the measurement by F-C's method, W-B's method was applied and from hemodynamical view point it was investigated to what extent does F-C's method influense upon psychosomatic state of patients.viii) Concerning to each case which reveals remarkable difference between W-B's values and F-C's, the possible causes were discussed. F-C's values show the averaged data during venesection, whereas W-B's values those estimated during only one cardiac cycle. F-C's values depends mainly upon the state of venous side while W-B's values chiefly upon that of arterial side. In consequence in the case of arrhythmia and congenital anomalies there are assumed to develop striking difference between two kinds of values estimated by F-C's method and W-B's.ix) It is a common defect of modern technique, not to be able to undertake F-C or W-B at the cardiopulmonary emergency. The maniplation of W-B's method can be performed simply and unbleedingly, sothat to the contrary of F-C's method, W-B's can be repeated in the same individual at every request. But W-B's method has of course the limitation of its applicating. Thus there is recognized the availability either in W-B's method or F-C's and. vice versa. Consequently in order to study the hemodynamics, it may be more ideal that both methods can be adopted at the same time but if there is a circumstance under which one of them can only be applied, it is hoped that the superiority of two methods must be utilized according to each aim of examination.
