Figures & Tables

Figure 1:

The four ventricle models. The blood is displayed in red and the ventricle is semitransparent red. The surrounding lung tissue is not shown.

Figure 2:

LVV during one cardiac cycle. The first three models are simulated for volume increments of 5 mL, while the physiological model is only available for the 5 indicated volumes.

Figure 3:

Simulated admittances show a non-linear correlation with the LVV. Admittance magnitude (top) and admittance phase (bottom).

Figure 4:

Simulated admittances correlate strongly with the LVV throughout a cardiac cycle. Admittance magnitude (top) and admittance phase (bottom).
