8.8.4 Saving the Current QTc as Reference
In order to quantify changes in the QTc value, you can set a QTc reference.
To set the current values as reference:
1. Select the ECG parameter window or waveform area to enter the [ ECG Setup ] menu.
2. Select the [
QT Analysis >>
] tab.
3. Select [
Save Ref.
]. This QTc will then be used to calculate QTc.
8.8.5 Changing QT Settings
8.8.5.1 Setting QT Alarm Properties
To set QT alarm properties:
1. Select the ECG parameter window or waveform area to enter the [
ECG Setup
] menu.
2. Select the [ QT Analysis >> ] tab.
3. Set QTc and QTc alarm properties.
8.8.5.2 Selecting Leads for QT Calculation
You can select one lead or all leads for QT calculation.
To select leads:
1. Select the ECG parameter window or waveform area to enter the [ ECG Setup ] menu.
2. Select the [
QT Analysis >>
] tab.
3. Set [
Analysis Lead
]. [
All
] is selected by default. This means all leads are used for QT
calculation.
8.8.5.3 Selecting the QTc Formula
The monitor uses the Hodges correction formula by default to correct the QT interval for
heart rate.
To select the QTc formula:
1. Select the ECG parameter window or waveform area to enter the [
ECG Setup
] menu.
2. Select the [ QT Analysis >> ] tab.
3. Set [ QTc Formula ].
