It consists of two periods: one during which the heart muscle relaxes and refills with blood, called diastole, following a period of robust contraction and pumping of blood, called systole.After emptying, the heart relaxes and expands to …
WebThe period of time that begins with contraction of the atria and ends with ventricular relaxation is known as the cardiac cycle (Figure \(\PageIndex{1}\)).The period of contraction that the heart undergoes while it pumps blood into circulation is called systole.The period of relaxation that occurs as the chambers fill with blood is called diastole. WebThe cardiac cycle comprises a complete relaxation and contraction of both the atria and ventricles, and lasts approximately 0.8 seconds. Beginning with all chambers in diastole, blood flows passively from the veins into …

WebAbstract. We hypothesized that during chick embryo cardiac development, cycle length decrease (heart rate increase) may be associated with developmental changes in the ventricular relaxation rate constant, tau, which can be estimated from ventricular pressure decrease by the function P (t) = P0e-t/tau, where P0 = pressure at the time of minimum ...
