Description
Advanced Triggering
Triggered modes allow for
techniques.
To use these modes:
1. The patient must be connected to electrocardio-
graphic leads or an external source of the ECG
waveform, or R-wave trigger must be connected to
the system.
2. The study must be a stress protocol.
Triggered acquisition modes may be restricted to
specific protocols, such as stress echocardiography
and contrast imaging.
Press the corresponding Soft Window knob to dis-
play the triggering options: Beats, Frames or Time.
Press the knob to display the triggering options
and then turn the knob to adjust the setting.
As with any echocardiographic technique
NOTE:
that uses ECG triggering, for this process to func-
tion properly a stable and reliable waveform or trig-
ger must be detected by the system. Artifacts or
other irregularities such as arrhythmias may cause
problems in the detection of trigger points such as
the R-wave.
To resume normal scanning when you are
NOTE:
finished using the Advanced Triggering option, be
sure to reset the Beat, Time, and Frames values to
their lowest value.
In intermittent imaging mode, the system scans only
on the selected heartbeats. Press the correspond-
