Popis: We performed a computer simulation of four bouts of successive left-sided heart failure aggravated at intervals of one week. Each bout resulted in a decrease in the level of the left ventricular output curve to 70% of the preceding output curve level, while the right ventricular output curve was maintained unchanged. At each bout of acute left-sided heart failure, there occurred a transient oliguria and a gradual increase in the left atrial pressure. When the ordinate was the pulmonary “venous” volume and the abscissa was left atrial pressure, the pulmonary “venous” volume and left atrial pressure increased linearly (obliquely to the right), with progress of left-sided heart failure every week. By definition, the unstressed volume of the pulmonary “venous” system was unchanged.
