一项实验室研究旨在调查独立的泵样功能的狗的心脏右心室。收缩期和舒张期肺动脉压波动作为泵送效率的决定性标准。将控制压力水平与电刀凝固游离右心室心肌完全损伤后记录的压力水平进行比较。由此产生的损伤程度是通过心电图、生理和组织学观察分析确定的。结果被讨论和解释在一个假设机制的基础上，个别心室肌束的结构。
A laboratory study designed to investigate the independent pump-like function of the right ventricle of the dog heart is presented. Systolic and diastolic pulmonary arterial pressure fluctuations were used as the definitive criterion for pumping efficiency. Control pressure levels are compared with those recorded after complete damage, by electrosurgical coagulation, of the free right ventricular myocardium. The degree of damage so produced was ascertained from an analysis of electrocardiographic, physiologic and histologic observations. The results are discussed and explained in terms of a postulated mechanism based upon the architecture of the individual ventricular muscle bands.
