Model Free Wall Elastance Curves with Loss of Neural Feedback. RVF and LVF elastance curves with no baroreflex-mediated augmentation of contractility (Panels A1-A2) (model parameter Fcon), and with no heart rate neural control (Panels B1-B2) (model parameters FHRs and FHRv). With Fcon fixed at mean steady state control levels and no feedback control, RVF elastance does not change, peak elastance remains same as control in all cases. LVF elastance with R-type LVDD exhibits slower rise to peak (unseen in elastance with Fcon in Figure 8). With no FHRs and FHRv, heart rate is unchanged with LVDD.
