AutoEF is performed on either one or both apical 4-chamber or
2-chamber views, in any order.
The result is presented as Ejection Fraction value for each view
and average Ejection Fraction for the whole LV are stored to
the worksheet.
Note: AutoEF tool is intended for adult cardiology and is not
intended to be used in pediatrics cardiology. AutoEF tool is
therefore only available when using the following probes:
M4S-RS (on Vivid S6 only), 3S-RS, 5S-RS.
Acquisition
1. Create an exam, connect the ECG device and make sure
to obtain a stable ECG trace.
2. Acquire 2D grey scale cineloops of an Apical 4 chamber
view and an Apical 2 chamber view.
• The frame rate should be between 35 and 100 frames
per second. A higher frame rate is recommended for
high heart rate.
• The scanner should be configured to store at least
100 ms before and after each heart cycle.
• If the acquisition has more than one heart cycle, the
analysis will be done on the second last heart cycle.
• The entire myocardium should be visible.
• A depth range that includes the entire left ventricle
should be used.
Starting AutoEF
1. Open any one of the stored views and press MEASURE.
2. In the Measurement menu, select AutoEF. The View
selection menu is displayed (Figure 7-25).
