Forward and backward waves at the aortic root: Steady-state and wave re-reflection considerations

Background: The assumption of steady-state oscillation is often overlooked when arterial pressure and flow waveforms are decomposed into backward (Pb) and forward waves (Pf). This has led to various misinterpretations including a significant reflection-free time during early-systole and attribution of the Pf to solely a product of left ventricular contraction and proximal aortic properties.
