When performing AFI on all three apical views the following
results are also available:
• Review screen (Figure 7-20) displaying:
• 3 processed apical views
• Bulls-Eye with different user-selectable presentations
(see "Bulls-Eye presentation" below).
• BE+Traces screen (Figure 7-21) displaying:
• Segmental curves for each three Apical views
• Bulls-Eye with different user-selectable presentations
(see "Bulls-Eye presentation" below).
• Single Bulls-Eye screen (Figure 7-22) displaying:
• Bulls-Eye with different user-selectable presentations
(see "Bulls-Eye presentation" below).
• Global Strain (GS) values for all three apical views.
In a given view the Global Strain (GS), also called Global
Longitudinal Peak Strain (GLPS), is defined as the
percentage of maximal contraction over the whole cardiac
cycle of the entire myocardial wall relative to its end
diastolic length.
• Averaged global Peak strain value from all three apical view
data.
• AVC measurement (either automatic, event timing
measurement or manual ("AVC Timing Adjustment" on
page 284).
• APLAX heart-rate
Bulls-Eye presentation
The Bulls-Eye in the different screens displays the Peak
Systolic strain presentation. It shows the segmental Peak
systolic strain (PSS) color coding (different shades of blue-red)
with segmental Peak systolic strain values and other
calculations.
Note: The Bulls-Eye can be configured to display either 18 or
17 segments (from Config/Meas-Text/Advanced/ AFI Segment
model)(Figure 7-15).
Note: The system can be configured so that the user can also
choose to display Post systolic index (PSI) color coding and
segmental PSI values in the Bulls-Eye (from
