PACEMAKER PROCESSING
You can select pacemaker processing, ST Analysis, or neither for a patient, but not
both. These two processes are mutually exclusive functions.
WARNING: Always set Process to Pacer for patients who have working electronic pace-
makers. Do not set Process to Pacer for patients who do not have an elec-
tronic pacemaker.
Press the Process button on the Patient Settings screen to toggle through Pacer, ST, or
None.
Note: The Pacer button is not available if a 3-Wire device type is selected. Pacer
Processing is not available for 3-Wire ambulatory patients.
CAUTION: If you select Pacer, no ST alarms are triggered.
Pacemaker Detection
Pacemaker pulses are detected by the bedside monitor or ambulatory transceiver and
sent to the Central Station, which processes pacemaker data in the same way for both
ambulatory and bedside patients. See page 90 for instructions on how to make pace-
maker settings.
Note: False beat detections can be caused by low amplitude artifact on paced
patients. To eliminate false beats, reposition the LA electrode. See “Patients
with a Pacemaker” on page 49.
Pacemaker Analysis
When pacemaker analysis is enabled in the Central Station, the central “looks” for the
encoded pacemaker flag in the digital ECG data. The system indicates where pace-
maker pulses were detected by inserting a pacemaker flag in the ECG data. The pace-
maker flag is displayed in a selected color in order to easily distinguish the pacer flag
from the background ECG. The pacemaker flag is represented in printed ECG data as
a thick 10 mm line (See Figure 41 on page 96).
Note: The PatientNet System complies with the Pacemaker Detection requirement
per ANSI/AAMI EC-13 Cardiac monitors, heart rate meters, and alarms. We
do not validate specific pacemakers. If the pacemaker does not produce
pacer pulses at the skin within the parameters described under ANSI/AAMI
EC-13, then the DT 4000 or DT4500 may not be able to detect the pacemaker.
WARNING: Close surveillance of patients that have a pacemaker is required.
