b. Place the ECG electrodes on the patient’s body (as shown in the following figure).
2. Tap [Physio] to enter physio operation interface.
3. Switch the imaging modes and display formats, adjusting the parameters to get an optimized
image.
4. Parameter adjusting:
In image menu, tap [ECG] to enable or disable ECG waveform curve. Adjust the [Speed],
[ECG Gain], [Position] and [Invert].
5. Trigger:
Tap [Trig Mode] to open the triggering function and set the trigger time.
6. Freeze the triggering image and the curve, and then review them.
7. Exit ECG mode, and remove ECG electrodes from the patient.
ECG Triggering
ECG triggering means that image scanning is activated at some time points of ECG signals, thus
obtaining B images at these time points. The triggering image should be in 2D-mode.
When ECG triggering occurs, some marks (frame triggering mark) appear on the ECG waveform
(relative R wave, the time for delay set), indicating the time points when the 2D images are
captured.
TIP:
• The triggering mark is displayed in both freeze mode and live mode
• The marks in Dual trigger are in different colors.
• Triggering function is unavailable if the ECG trace is disappeared. Only the live 2D image can
be triggered.
• No delay time or time interval shall be less than the time required to scan a single image.
• If the delay time is longer than a heart cycle, then the heart cycle in the delay time is omitted,
that is to say no trigger is occurred when R waveform is detected in the duration.
Triggering Mode
This system supports single trigger.
