The author investigated the change of venous wave or auricular wave before and after artificial Pneumothoraces in patients of pulmonary tuberculosis or in dogs, and obtained following results. (1) Depth of X-valley in venous wave decreased after Pneumothorax and increased after discharge of air from pleural cavity. This was also the case in S_m-wave of auricular wave. (2) When large amount of air was introduced continuously or cumulatively, depth of S_m-wave decreased not in linear but in parabolical relation to the amount of air introduced. (3) Both before and after Pneumothorax, when preceding cardiac cycle was long, S_m-wave or X-valley denotes the suction-power of heart (s. 1st report), these experimental results show that suction-mechanism of heart is closely related to pulmonary suction-mechanism.
