Several models of the coronary circulation have been proposed, relating arterial flow waveform and cardiac contraction. Some of them have produced new concepts, such as back pressure, and zero flow pressure, founded on an over-simplified description of vascular collapse. Experimental studies have shown that the actual dynamics of a collapsible tube cannot be adequately described using a lumped parameter model. A distributed parameter model is therefore proposed and compared with the previous models.
已经提出了几种冠状动脉循环模型，将动脉血流波形与心脏收缩联系起来。其中一些模型产生了新的概念，如背压和零流压力，这些概念基于对血管塌陷的过度简化描述。实验研究表明，使用集总参数模型无法充分描述可塌陷血管的实际动力学。因此，提出了一种分布参数模型，并与先前的模型进行了比较。
