5.14 Stress Echo
CAUTION:
Stress echo data are provided for reference only, not for confirming a
diagnosis.
Stress Echo is an option, only the phased probes support stress echo function under the cardiac
mode.
5.14.1 Overview
The Stress Echo feature allows you to capture and review cardiac loops for multiple-phase
(multiple-stage) Stress Echo protocols.
Stress Echo data consists of Stress Echo loops, wall motion scores, and all other information
pertaining to the Stress Echo portion of a patient examination.
A loop is a clip that displays motion of a whole heart cycle or from beginning systole to end systole,
as indicated by the R-wave of the ECG trace and determined by the QT – Time Table.
The loops in a given protocol are acquired by stages (phases), according to stage configuration
(continuous (prospective) or retrospective (non-continuous)).
 Loops in non-continuous stages are limited to a specified loop-per-view maximum (such
as four). View labels can be selected only in the configured order. Acquisition is
retrospective; when you touch [Save Clip] on the touch screen or press <Save1>
(<Save2>) key on the control panel, the system saves the previously acquired images.
 Loops in continuous stages are limited by time rather than a maximum number of loops—
the system stops acquisition after two minutes. Acquisition is prospective; when you select
the stage label and then press <Save1> (<Save2>) key on the control panel, the system
starts saving newly acquired images. With this workflow, you assign view labels to the
loops after acquisition is complete, using controls on the Stress Echo screen to select the
"preferred" loop for each view.
When images are saved, the system places a green checkmark to the right of the view or
continuous stage and then shifts the red mark to the next view or continuous stage.
5.14.2 Stress Echo Acquisition Procedure
To acquire Stress Echo loops, you need to enable the ECG function.
1. Touch [Stress Echo] on the touch screen or press the customized key.
2. The system displays the Select Protocol window with protocol selections. Select the desired
protocol and then touch [Select].
The system displays the real-time imaging screen.
If the Stress Echo manual ROI option is selected in the Maintenance dialog box, then the
system also displays a region of interest (ROI). If Acquire Mode is set as Full-screen in
Maintenance, then no ROI box is displayed; for details, please refer to ―5.14.5 Maintenance
and Protocol‖.
3. If an ROI is displayed, adjust the ROI size and position, touch [Fix ROI] or press <Update> key
on the control panel to confirm the ROI.
Tips: When you confirm the ROI size by pressing <Update> or touch [Fix ROI], you cannot
adjust the ROI size during acquisition but only adjust ROI position through trackball.
4. Press <Save1> (<Save2>) key on the control panel to start acquisition.
The system displays the Protocol window on the left of the screen, listing the phases for the
selected protocol along with the views of the first phase (Phases are stages). The system
selects the first view for acquisition by default, indicating view selection by placement of a red
mark to the right of the view name.
5. Proceed through each view in each stage using the following instructions:
