8.11.3 12-Lead Setup
In the 12-lead screen, select [Setup] to enter the [12-Lead Setup] menu to change the settings related to 12-lead ECG
analysis. In the [12-Lead Setup] menu, you can also select [Report Setup>>] to set the format and contents of the ECG
reports.
12-lead Setup
Menu item Option Default Description
Filter Diagnostic, ST Diagnostic Set filter mode.
Note: The filter mode automatically switches to
[Diagnostic] when the patient monitor accesses the
12-lead -screen and resumes to the original setting
when the patient monitor exits the 12-lead screen.
Baseline Drift
Removal
On, Off On
Select whether the baseline drift removal (BDR)
process or 0.05-Hz filter is used.
[On]: BDR is enabled. This process suppresses most
baseline drift interference and also is able to
preserve the fidelity of the ST-segment level.
[Off]: BDR is disabled and the 0.05-Hz filter is used.
NOTE: BDR or 0.05-Hz selection applies to the
displayed ECG, printed report, analyzed and stored
data.
BDR introduces around 1-second delay. We
recommend use of BDR except when the delay is
unacceptable.
Both BDR and 0.05-Hz selections meet requirements
of the 1990 American Heart Association
Recommendations for Standardization and
Specifications in Automated Electrocardiography:
Bandwidth and Signal Processing pertaining to
lower-frequency response in electrocardiography.
Tachy High 80 - 130 100 Adjusts tachycardia threshold. Heart rates above the
setting are labelled Tachycardia.
Only applies to patients whose age exceeds 180
days.
Brady Low 40 - 60 50
Adjusts bradycardia threshold. Heart rates below
the setting are labelled Bradycardia.
Only applies to patients whose age exceeds 2191
days.
