1. Select an imaging mode that supports ECG triggering.
2. Tap the Physiology icon.
3. In the Live Monitoring section, ensure that Live Monitoring is on, and that ECG is enabled.
4. In the ECG column, adjust the range and offset so that the trace line fits these properties:

Note:
the image display, under Acquisition.
6. Tap t1 to activate the systole time slider control. The systole slider appears on the bar, and becomes
selectable.
7. While watching the image display, adjust the slider until you find the desired image in the cardiac
cycle. The system sets the selected time point on the R wave, and acquire one single frame of image
data during each cardiac cycle.
8. (Optional) To study the diastole time point within the cardiac cycle, tap t2 and follow the same
procedure to place a second trigger.
