Creating pressure-volume loop measurements in M-Mode
Pressure-volume (PV) loop measurements provide a graphical method of
identifying and evaluating LV pressure-volume relationship changes related to
dynamic levels of cardiac stress.
You can generate PV loops from LV area measurements on both B-Mode and
M-Mode images that are accompanied by a continuous blood pressure trace.
These traces are typically acquired from a blood pressure catheter.
This section describes how to obtain PV loops from M-Mode images.
f To obtain PV loops from an M-Mode image:
1. Create an M-Mode cine loop of the heart in a long-axis orientation.
2. Complete an M-Mode LV Area wall trace measurement (page 237) that
includes at least two cardiac cycles.
3. Right-click the measurement and select PV Curve.
Note: The PV Curve menu command is not available if the image does not include
blood pressure data.
