6-7
• ECG QRS signal is greater than1/3 of the Scale Indicator
• ECG Lead wire is positioned straight
• ECG ePOD is positioned outside of the field of view
• Ensure the ECG filter is appropriate for the MRI Scan
• Ensure SAR does not exceed 4 W/Kg
• ECG is selected to be displayed through Monitor Setup patient parameters menu
6.1.4. Changing ECG Settings
6.1.4.1. Trace A lead View
The ECG trace A is considered the primary ECG waveform and is the top position waveform
when both A and B waveform are enabled. The ECG trace A can display the following leads I,
II, III, V, AVL, AVF, AVR and CAL.
To adjust which lead is viewed on Waveform A follow these steps:
1. Touch the ECG vital sign box
2. Touch “Trace A” Lead
3. Select the desired lead (I, II, III, AVL, AVR, AVF, V, CAL)
4. Alternatively touch the ECG Filter description on above the ECG waveform
5. Touch Back Button to close the menu
NOTE
• The ECG derived heart rate is always calculated from Trace A even when a Trace B is
also displayed.
• CAL is not for clinical use
6.1.4.1.1. Trace B Lead View
The ECG Trace B is considered the secondary ECG waveform and is the lower ECG waveform
trace on the screen when enabled. The Trace B can display an additional waveform not
displayed in Waveform A.
To enable and or adjust which lead is viewed on Waveform B follow these steps:
1. Touch the ECG vital sign box
2. Touch “Trace B” Lead
3. Select the desired lead (OFF, I, II, III, AVL, AVR, AVF, V, CAL)
4. Touch Back Button to close the menu
6.1.4.2. Scale
The scale feature enables you to adjust the amplitude of an ECG waveform displayed.
To adjust the ECG scale, follow these steps:
1. Touch the ECG vital sign box
2. Touch Scale
3. Make Selection (5, 10, 15, 20, 25, 30 or 40 mm/mv)
(selection range is limited to 5, 10, 15 and 20 mm/mv with both trace A and B ON)
4. Touch Back button to close the menu
NOTE
• The ECG scale changes how the ECG waveform is displayed and has no effect on ECG
quality.
• Best results in MRI will be with the 5, 10, or 15 mm/mV scale
