The bracket situated to the left of the ECG waveform denotes 1 mv. If the ECG
waveform size is set to Auto, the bracket will auto-adjust to maximize the QRS
display, depending on signal amplitude.

This field enables/disables pacemaker pulse rejection circuitry.
Off: Use this setting for a patient without a pacemaker. All ECG events are
monitored; all complexes, including pacer spikes may be displayed
included in the heart rate calculation.
On: Use this setting for a patient who has a pacemaker. The monitor rejects the
pacer spike from the heart rate calculation and replaces the actual pacer spike
with a pacer event mark; in addition the letter
waveform speed. Following is an example of an MECG waveform with the
MECG pacer On.
