Figure 1 Schematic Representation of a Portion of the Elastic Ring During Diastole and Systole
The elastic ring is conceived to store energy in 2 different moments of the cardiac cycle: in diastole (ring expansion) and in the last part of systole (ring compression). The theoretic behavior of the elastic ring predicts that the energy stored by the ring would be returned at first during the onset of systole and later during the early diastolic phase, according to physiologic elastic behavior of a normal left ventricle (LV) chamber.
