.5.5 Setting Pacemaker Rate (For Mortara only)
Some pacemaker pulses can be difficult to reject. When this happens, the pulses are counted as a QRS complex and
could result in an incorrect HR and failure to detect some arrhythmias. You can set [ Pacemaker Rate ] to the pacemaker’s
rate in the [ ECG Setup ] menu. In this way, the patient monitor can calculate HR and detect arrhythmias more accurately.
When [ Paced ] is set to [ No ], the pacemaker rate cannot be set.

.5.6 Choosing an ECG Display Screen
When monitoring with a 5-lead or 12-lead set, you can select [ Others>> ]
→
[ ECG Display ]in the [ ECG Setup ] menu to
choose the screen type as:

[
Normal Screen
]: The ECG waveform area shows 2 ECG waveforms.

[ Full-Screen ]: The whole waveform area shows 7 ECG waveforms only.
When monitoring with a 12-lead set, you can also choose the screen type as [ 12-Lead ].
When the screen type is set to [ Normal Screen ], cascaded ECG waveforms can be displayed. To cascade ECG waveforms:
1. Select the [ Main Menu ]
→
[ Screens ]
→
[ Screen Setup ].
2. Select [ ECG1 Casc. ] in the second row. A cascaded waveform is displayed in two waveform positions.

.5.7 Setting the Notch Filter
The notch filter removes the line frequency interference. Only when [ Filter ] is set to [ Diagnostic ], the [ Notch Filter ] is
adjustable.
1. Select the ECG parameter window or waveform area to enter its setup menu. Then select [ Others >> ].
2. Set [ Notch Filter ] to

[ Strong ] when there is strong interference (such as spikes) with the waveform.

[ Weak ] when there is weak interference with the waveform.

[ Off ] to turn the notch filter off.
Set notch frequency according to the electric power frequency of your country. Follow this procedure:
1. When [ Notch Filter ] is set on, select [ Main Menu ]
→
[ Maintenance >> ]
→
[ User Maintenance >> ]
→
enter the
required password.
2. Select [ Others >> ]
→
[ Notch Freq. ] and then select [ 50Hz ] or [ 60Hz ] according to the power line frequency.

.5.8 Changing the Pacer Reject Settings
Select [ ECG Setup ]
→
[ Others>> ]
→
[ Pacer Reject ], and toggle between [ On ] and [ Off ].

When [ Pacer Reject ] is switched on, pace pulses are not displayed..

When [ Pacer Reject ] is switched off, pace pulses are displayed.
NOTE

When pace pulses are detected, pace pulse marks “|” are shown on the ECG waveforms. Pacer Rejection
setting has no impact on the display of pace pulse marks “|”
