Study of Hemodynamic Parameters Using Phase Analysis of the Cardiac Cycle

摘要

The circulatory system is a unique biological transport system. The activity of the circulatory system obeys strict natural laws. The hemodynamic parameters are the main parameters of circulatory system activity. There are many invasive and noninvasive methods for measurement of minute and stroke blood volume [1]. One of the disadvantages of these methods is considered in this work. Other disadvantages of these methods are beyond the scope of this work. Minute and stroke blood volumes give information about integral hemodynamic parameters. Energy expenses of heart and blood vessels cannot be derived from minute and stroke blood volumes. More effective methods include evaluation of not only integral parameters (minute and stroke blood volumes) but also phase hemodynamic parameters (phase blood volume imported into the heart and ejected from the heart per cardiac cycle phase).
