Figure 3 The temporal pattern of the normalized values for MAA, TMP and ROA are shown for four representative patients. In all patients there is a biphasic pattern for ROA with a rapid decrease from its early systolic peak and a rapid increase toward its late systolic peak with a midsystolic decrease. Although MAA also peaked in early and late systole, its changes were more gradual and over a narrower range. In contrast, TMP showed wide and rapid changes in early and late systole mirroring the time course of ROA.
