ECG Size
This option enables you to change the size of all the ECG waveforms displayed
on the screen. This may be necessary when diagnosing or problem solving.
Normal size (1X) is recommended unless circumstances require otherwise.
NOTES:
If a size other than 1X is used, the size is displayed on the left side
of the screen next to the ECG waveform.
Size 2X and greater will lower the QRS detection threshold. This
may be helpful for low amplitude QRS waveforms.
Use with caution
since baseline artifact may be detected as a QRS.
Follow this procedure:
1. Select ECG SIZE option from the ECG Menu. A popup menu opens
showing all sizes available. The current size of all displayed ECG
waveforms is highlighted.

2. Rotate the Trim Knob control to change the size.
The change occurs
immediately on the screen and affects all displayed ECG waveforms.
3. When you are satisfied with your selection, press the Trim Knob control
to close the popup menu.
NOTE: For QRS complexes < 1 mV, use size 2x or 4x.
