Figure 5.

Relative pressure and volume differences after onset of mechanical support. The figure reflects the immediate changes in left ventricular pressures, volumes and native cardiac output as well as stroke volume by comparing the first time point after onset of mechanical support (t = 5) with the previous measurements (t = −20) as percentage of relative change for both devices. ESP, Left ventricular end systolic pressure; ESV, Left ventricular end systolic volume; EDP, end diastolic pressure; EDV, Left ventricular end diastolic volume; NCO, native cardiac output; SV, left ventricular stroke volume.
