乳头肌是心脏学科常用的研究标本,将乳头肌放在灌流装置中进行人工灌流,通过换能器即可记录其机械活动。研究乳头肌等长收缩力学性能和顺应性的灌流记录装置,必须具备下述两个条件: 1.准确记录乳头肌的静息张力和主动张力:静息张力(RT)是研究顺应性的基本参数;
Papillary muscles are commonly used in cardiac research specimens, the papillary muscles in the perfusion device for artificial perfusion, through the transducer to record its mechanical activity. The perfusion recording device that studies the isometric mechanical properties and compliance of papillary muscle must meet the following two conditions: 1. Accurately record the resting tension and active tension of the papillary muscles: resting tension (RT) is the basic study of compliance parameter;
