本文观察了8只犬缺氧停搏后心包对左心室压力-容积曲线的影响。采用大容量脑室内球囊。发现心包在研究的整个压力范围（0-20 cm）内升高左心室压力并减少容积。H2O）。在10 cm处切除心包。H2O使LV压力降低4.6 ± 1.0 cm。H2O，以及额外的6.2 ± 1.1 cc./一百克。需要LV将压力恢复到其先前值。在20厘米处。H2O压力降低6.8 ± 2.0 cm。水13.6cm处的体积变化。H2为7.2 ± 1.6 cc。/一百克。LV.这些数据得到了先前发表的结果的充分证实，并支持这样的观点，即在正常舒张末期容积下，心脏由具有大顺应性和充足弹性的心包包膜轻轻支撑。
The effect of the pericardium on the pressure-volume curve on the left ventricle has been studied following anoxic arrest in eight dogs. A large volume intraventricular balloon was employed. The pericardium is found to elevate left ventricular pressure and reduce volume over the entire range of pressures studied (0–20 cm. H2O). Removal of the pericardium at 10 cm. H2O reduces LV pressures 4.6 ± 1.0 cm. H2O, and an additional 6.2 ± 1.1 cc./100 gm. LV are required to restore pressure to its previous value. At 20 cm. H2O pressure is reduced 6.8 ± 2.0 cm. H2O. The volume change at 13.6 cm. H2is 7.2 ± 1.6 cc./100 gm. LV. These data are well substantiated by previously published results and support the view that at normal end-diastolic volumes, the heart is gently supported by a pericardial envelope of large compliance and ample elasticity.
