11.3.2 Wall Motion Scoring
The WMS-Report lists user-assigned wall motion scores and associated data.
The Wall Motion Score (WMS) measurement is an application prepared for assisting in stress echo
semi-quantitative evaluations of abnormalities with left ventricular wall motion or changes in wall
thickness. The left ventricle is divided into segments for scoring to evaluate the degree of
abnormality from the sum of the scores in each segment using the motion of the walls of the entire
left ventricle.
You can assign wall motion scores to specific portions within each view (representative loop). You
can also assign a normal wall motion score (WMS) to the currently selected view or to all displayed
views.
Two methods of chamber segment division, ASE 16 and ASE 17, are supported. In addition, each
segment has 3 kinds of scoring method: 4, 5 and 7 points. Select through the [Scoring] control on
the touch screen.
To assign a wall motion score (WMS):
1. Select a colored number.
The meanings and colors used in segments are listed in the table below.
2. Use the trackball to select the value and then click the target segments, then the segment is
assigned with a value.
Item Description
Review/WMS Perform side-by-side comparison of the same views at different stages
(PLAX, PSAX, A4C, A2C at “Rest” compared to PLAX, PSAX, A4C, A2C
“Post-Exercise”). Clips are synchronized.
• Under [Text] “Off” status, when you select one stage, all view loops are
displayed on the screen; when you select one view, all loops of the same
view in different stages will be displayed on the screen.
• Set [Text] to “On”, the system will select loops of first two views of the
first two stages to display automatically. If you choose [Previous], then
loops of the next two views of the first stages will be displayed. If you
choose [Next], loops of the first two views in the 3rd and 4th stage will be
displayed.
In the meantime, if you choose one stage, loops of all views under this stage
will be displayed on the screen (4 at most), and choosing one view will lead to
loops of this view in different stages be displayed (4 at most).
Display Selected Displays loops of all the stages and views selected.
