Fhf2WT/Y pericardium axial motion vs. time at a) 38, b) 40 and c) 41°C using the ROI indicated in Fig. 4h. The motion was stable from beat to beat. A respiration artifact from was visible in (b) and (c) causing a drift in the local mean value over time. The time points from Fig. 4 are noted by vertical lines in (a).
