4. The system calculates the pressure-volumes of the cardiac cycles and plots
them as a graph on the Pressure Volume Relationship window.
Pressure-Volume relationship graphs
When you have generated pressure-volume graph data, you can use the tools on
the Pressure Volume Relationship window to:
Display the end systolic PV points
Display the end diastolic points
Display a loop that represents a virtual or averaged cardiac cycle
Toggle the horizontal dimension between Volume and the basic dimension of
the loops
Export the pressure-volume relationship data
ESPVR check box
Check this box to display the end systolic PV points.
If the graph displays a single loop, the system plots a green
dot on the curve at the End Systolic point.
If the graph displays multiple loops, the system plots a best-fit line
through the End Systolic points.
EDPVR check box
Check this box to display the end diastolic points.
