Abstract [en]

This chapter analyzes papillary muscle mechanics for a mythical "PORVINE" heart created by superimposing PORcine and oVINE data. Porcine data were obtained from the LVP and papillary force curves in Figure 3 of Askov et al.1, digitized and interpolated with a cubic spline function. Ovine data are from our F10 heart, selected solely because the F10 LVP waveform was very similar to the LVP curve shown in Askov et al.1 Systolic duration was roughly matched by assigning a sampling interval of 15 ms to the ovine data, rather than the actual sampling interval of 16.67 ms. The porcine data were then sampled at these same 15 ms intervals. The resulting LVP, papillary force, and papillary length curves are shown in Figure 22.1, with magnitudes scaled or translated, as necessary, to fit the <0-9> ordinate. Additional ovine data, with time- but no magnitude-scaling, are shown in Figures 22.2, 22.5, and 22.6. Figure 22.7 shows the original data used to construct Figure 22.1.
