8.5.5 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.
8.5.6 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.
8.5.7 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.
8.5.8 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 “|”
