Vpeak measurement
This tool enables the user to generate a tissue velocity profile
for a given wall segment through the entire heart cycle and
display color-coded Vpeak in tissue.
From the velocity trace, the user can determine whether the
systolic Vpeak is over or under a clinically determined velocity
threshold (see "References" on page 224) to confirm the wall
motion scoring.
To display a Vpeak measurement
1. Perform segment scoring as described on page 216.
1. Vpeak measurement (V-peak measurement is displayed in views from peak levels and only after
scoring.)
2. Tissue Tracking
3. Quantitative analysis
CAUTION
QTVI Stress can be used only in conjunction with wall motion
scoring analysis, as a guiding tool.
When activating QTVI Stress, the measurement applies only to
the currently highlighted segment for the current level and
projection view.
