8.5 Changing ECG Settings
8.5.1 Setting Pacemaker Rate (For Mortara Only)
Some pacemaker pulses cannot be rejected. When this happens, the pulses are counted as a
QRS complex and could result in an incorrect HR and a failure in detecting some
arrhythmias. Select [
ECG Setup
] → [
Others >>
], and you can set [
Pacemaker Rate
] to the
pacemaker’s rate in the popup 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.
8.5.2 Choosing the Alarm Source
In most cases the HR and PR numerics are identical. In order to avoid simultaneous alarms
on HR and PR, the monitor uses either HR or PR as its active alarm source. To change the
alarm source, select [
Alm Source
] in the [
ECG Setup
] menu and then select either:
„ [
HR
]: if you want the HR to be the alarm source for HR/PR.
„ [
PR
]: if you want the PR to be the alarm source for HR/PR.
„
[
Auto
]: If the [Alm Source] is set to [Auto], the monitor will use the heart rate from
the ECG measurement as the alarm source whenever the ECG measurement is
switched on and a valid heart rate is available. If the heart rate becomes unavailable,
for example if leads becomes disconnected, and a pulse source is switch on and
available, the monitor will automatically switch to Pulse as the alarm source. When the
Leads Off condition is corrected, the monitor will automatically switch back to the
heart rate as the alarm source.
8.5.3 Choosing a 5-Lead ECG Display Screen
When monitoring with a 5-lead set, you can, in the [
ECG Setup
] menu, set the [
ECG
Display
] screen to:
„ [
Normal
]: The ECG waveform area shows 2 ECG waveforms by default. You can
select 3 ECG waveforms for display.
„ [
Full-Screen
]: The whole waveform area shows 7 ECG waveforms only.
„ [
Half-Screen
]: The upper half part of the whole waveform area displays 7 ECG
waveforms.
