2. Fig. 1
Example of waveform data during inferior vena cava (IVC) occlusion from 1 patient with a left ventricular assist device (LVAD). The electrocardiogram, right ventricular (RV) pressure, RV area, first derivative of RV area (dA/dt), LVAD volume, and first derivative of LVAD volume (dV/dt) (ie, LVAD filling) are shown.

3. Fig. 2
Superimposed left ventricular assist device (LVAD) filling profiles from several cardiac cycles from 1 patient during inferior vena cava occlusion. (dV/dt = first derivative of LVAD volume, ie, LVAD filling.)
