Two phases of the cardiac cycle
WebThe cardiac cycle includes two phases: diastole and systole (Fig. 1.4). In the diastole phase, blood returns to the heart from the superior and interior vena cava and flows into the right … WebUsing radiometric techniques, the volume and shape of the heart can be imaged in real time, as can the volume of blood that passes through the heart during each part of the cardiac cycle. This data can be combined to generate a pressure-volume diagram for the left-ventricle, corresponding to a single, full cardiac cycle (Figure 2).
