 [
Auto
]: If the [
Alm Source
] is set to [
Auto
], the monitor will use the heart rate from the ECG measurements as the
alarm source whenever a valid heart rate is available. If the heart rate becomes unavailable, for example the ECG
module is turned off or becomes disconnected, the monitor will automatically switch to PR as the alarm source.
8.5.3 Setting the ECG Lead Set
You can set the [
Lead Set
] by selecting [
ECG Setup
]
→
[
Others>>
]. You can set the [
Lead Set
] as [
Auto
] if the auto lead
detection function is available.
8.5.4 Choosing an ECG Display Screen
When monitoring with a 5-lead set, you can select the [
Screens
] Quickkey. In the [
Choose Screen
] window, choose the
screen type as:

[ Normal Screen ]: The ECG waveform area shows 2 ECG waveforms.

[ ECG 7-Lead Full-Screen ]: The whole waveform area shows 7 ECG waveforms only.

[ ECG 7-Lead Half-Screen ]: The upper half part of the whole waveform area displays 7 ECG waveforms.
When the screen type is set to [ Normal Screen ], cascaded ECG waveforms can be displayed. To cascade ECG waveforms:
1. Select the [ Screens ] Quickkey
→
[ Screen Setup ].
2. Select [
ECG1 Casc.
] in the second row. A cascaded waveform is displayed in two waveform positions.
8.5.5 Changing the ECG Filter Settings
The ECG filter setting defines how ECG waves are smoothed. To change the filter setting, select [
Filter
] from [
ECG Setup
]
and then select the appropriate setting.

[ Monitor ]: Use under normal measurement conditions.

[ Diagnostic ]: Use when diagnostic quality is required. The unfiltered ECG wave is displayed so that changes such as
R-wave notching or discrete elevation or depression of the ST segment are visible.
 [
Surgery
]: Use when the signal is distorted by high frequency or low frequency interference. High frequency
interference usually results in large amplitude spikes making the ECG signal look irregular. Low frequency
interference usually leads to wandering or rough baseline. In the operating room, the surgery filter reduces artifacts
and interference from electrosurgical units. Under normal measurement conditions, selecting [
Surgery
] may
suppress the QRS complexes too much and then interfere with ECG analysis.

[ ST ]: Use when ST monitoring is applied.
Warning

The [Diagnostic] filter is recommended when monitoring a patient in an environment with slight
interference only.
