Figure 7-19: 4-ch and 2-ch Parametric systolic strain images
Results
For the APLAX and apical 4-chamber views the following
results are available:
• Single screen (Figure 7-17) displaying a 2D image with
strain parametric data.
• Quad screen (Figure 7-18) displaying:
• 2D image with the ROI
• 2D image with Peak systolic strain parametric data
• Curved M-Mode image with strain data
• Segmental curves
• ECG trace and "QuickTip" help
CAUTION
If auto-AVC is used as AVC timing calculation method when
running AFI ("AVC Timing Adjustment" on page 284), the strain
values displayed in the Quad screen for the APLAX and 4
Chamber views may differ from the strain values obtained after
the system has performed the final calculation from all three
views. The reason for this is that the Auto-AVC calculation
derived from all three views is most accurate and may be
different from the intermediate AVC calculations used for each
view. The strain values displayed in the Quad screen on APLAX
and 4 Chamber views are therefore preliminary values. Only final
strain values should be reported.
If you enter Quad screen again after all three loops have been
processed, the strain values will be correct.
