### CCCC.4.4 Cardiac Cycle Point

Note that (SRT, F-32020, "Systole") is used here to refer to the entire duration of ventricular systole, while (SRT, R-FAB5B, "End Systole") is used to refer to the point in time where the aortic valve closes (or in the case of the right ventricle, the pulmonary valve). Therefore, a Vmax measurement for systole would mean the maximum velocity over the period of systole, and a Vmax measurement for end systole would mean the maximum velocity at the time point of end systole.
