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 reference 1 on page 7-25) to confirm the wall
motion scoring.
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.
