Abstract

After a brief discussion on the basis of the dilution method for determination of telediastolic volume (TDV) of the ventricles, the authors described the results from their own experimental studies on 8 nonbred dogs, on whom 186 curves of indicator "washing" (of the dye "Cardiogreen" were recorded, presented on 2 tables. The results showed that the measurements should be made by means of the later steps of the curves. TDV and accordingly the relative stroke volume of both ventricles differed slightly. The smaller values, according to the authors, of TDV of the left ventricle in comparison with the right ventricle revealed that the size of the relative stroke voluem depended both on the mechanism of Starling and on the contractility of the ventricles.

摘要

在基于稀释法测定心室舒张末期容积(TDV)进行简短讨论后,作者描述了他们对8只未杂交犬进行的实验研究结果,记录了186条指示剂“洗脱”曲线(染料“Cardiogreen”的曲线),列于2个表格中。结果表明,测量应采用曲线的后期步骤。两个心室的TDV以及相应的相对每搏输出量略有不同。作者称,左心室TDV的值比右心室小,这表明相对每搏输出量的大小既取决于斯塔林机制,也取决于心室的收缩性。
