WebSystolic Time Intervals A systolic dysfunction leads to an increase in the pre-ejection period (PEP, or the time interval between the Q wave and the beginning of ventricular ejection), a decrease in the ventricular ejection duration (ejection time, or ET), and therefore an increase in the PEP/ET ratio [44,45]. WebThese systolic time intervals can be obtained from a right parasternal short axis transaortic TM view with good visualization of the aortic valvular leaflets movement [46] or from a spectral wave Doppler of the aortic flow [47] (Figure 7-8).
