ECG 7-3 
7.2 Parameter Description 
Parameter  Description 
ECG 
Function: to control the display of ECG trace in live status. 
Value: On/Off, On is to display the trace, while Off is to hide the trace. 
In scanning mode, turn off ECG display will stop ECG signal acquisition. 
In freeze mode, this is used to show or hide the ECG trace. 
ECG 
Source 
Select ECG source.   
ECG Gain 
Function: to set the amplitude of ECG trace. 
Method: click [Gain] in the soft menu or menu. 
Value: 0-30, in increments of 1. 
ECG 
Position 
Function: to set the vertical position of the ECG trace on the image display. 
Method: click [ECG Pos] in the soft menu or menu. 
Value: 0%-100%, in increments of 5%. 
Speed 
Function: change the speed of the physio trace. 
Value: 1-6 
The refresh speed of the physio signal on B image is independent from the 
refresh speed of timeline refresh speed (M mode, PW and CW mode) 
7.3 ECG Review 
When an image is frozen, the ECG waveform will be frozen at the same time. When 
images are reviewed with the ECG electrodes connected, the ECG waveform is the 
reference for time. 
After the images are frozen, all real time images are in the status of linked review. 
The frame position marker indicates the time relationship between the currently reviewed 
2D image and the ECG trace or M/D image.
