The slide shows the instantaneous coronary blood flow (CBF) waveforms in different circulatory conditions. Upper panel shows the instantaneous CBF waveforms measured (dashed black line) and simulated (red line) before caval occlusion. Lower panel reproduces the CBF waveforms (in vivo and simulated) at the end of the caval occlusion manoeuvre.The simulated CBF, in the lower panel, presents two local minimums (labels A and C). It is possible to observe the presence of an inflection point in experimental data between the local minimums in simulated data.
