自从Morixz等人(23)的工作以来，许多研究人员一直在研究静息和肌肉工作期间心脏体积的变化。关于早期文献的调查见McCrea，Eyster和Meek(21)和LiQestrand，Lysholm和Nylin(20)，现代研究见Rushmer(33)。在少数研究中，这种方法允许计算心脏体积。正如Liljestrand等人指出的那样，只有在两个直角的平面上同时拍摄X光片时，这种计算才能充分进行(20)。人们对动态肌肉工作期间心脏体积变化的巨大兴趣的主要原因一直是对斯塔林定律是否适用于解释正常心脏在运动中表现的增强的持续讨论。根据传统的概念，运动时的心输出量是通过心率和每搏量的增加来增加的。请参阅Reindell
The variations of the heart volume at rest and during muscular work have since the works of Morixz et al.(23) been studied by many investigators. For surveys of the earlier literature see McCrea, Eyster and Meek (21) and LiQestrand, Lysholm and Nylin (20), and of modern studies see Rushmer (33). In only a few of the irtvestigations have the methods allowed it computation of the heart volume. Such calculations can be performed adequately only if roentgenograms are taken simultaneously in two planes at right angles, as pointed out by Liljestrand et al.(20). The main cause of the large interest in the changes of the heart volume, during dynamic muscular work, has been the maintained discussion of the applicability of Starling’s law to explain the increased performance of the normal heart during exercise. According to, traditional concepts cardiac output during exertion is increased by increases in both heart rate and stroke volume (for ref. see Reindell
