Abstract

Coronary artery flow is complex. Flow in this system is divided into systolic and diastolic. However, systolic flow should be divided into two phases, isovolumetric and the ejection phase, since these two components are determined by completely different parameters. Flow through the myocardium is affected by the close mechanical coupling between myocytes and capillaries effected by the array of collagen struts and their disposition. This latter provides the anatomic arrangement that makes possible the integrated "massaging" effect postulated by Wiggers (26).

摘要

冠状动脉血流很复杂。该系统中的血流分为收缩期和舒张期。然而，收缩期血流应分为两个阶段，等容收缩期和射血期，因为这两个部分由完全不同的参数决定。流经心肌的血流受心肌细胞与毛细血管之间紧密机械耦合的影响，这种耦合由一系列胶原支柱及其排列方式实现。后者提供了解剖学结构，使威格斯（26）所假设的综合“按摩”效应成为可能。
