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 in the bottom-right area of the screen.
