Use the Propaq CS Monitor With Pacemaker Patients
Warning
Pacemaker signals can differ from one pacemaker to the next. The Association for Advancement of Medical
Instrumentation (AAMI) cautions that “in some devices, rate meters may continue to count the pacemaker rate during
occurrences of cardiac arrest or some arrhythmias. Do not rely entirely upon rate meter alarms. All pacemaker patients
should be kept under close or constant observation.”
The presence of much pacer-like noise can cause the displayed heart rate to be erratic even though the ECG
trace may look undistorted with the pacer indicator off. To help avoid this noise problem, use fresh ECG electrodes and
make sure the ECG cable lead wires make good connections.
If the patient being monitored has a pacemaker, the Propaq CS monitor detects and can indicate the
occurrence of pacemaker signals.
1.
To access the monitor pacer indicator, from the Main Menu press
ECG/RESP, MORE,
and then
NEXT
to select the PACER DISPLAY.
2.
Press
CHANGE
to set the PACER DISPLAY either ON or OFF.
When ON, the monitor displays (and prints on printouts) vertical dashed lines to indicate
each time a pacemaker signal is detected. (If the pacemaker signal is strong enough, the
monitor also displays it as a waveform “spike.”)
When OFF, the vertical lines are not displayed (or printed), but the pacemaker signal
waveform spike is still displayed if strong enough.
Note
Pacemaker pulses are not counted as heartbeats as defined by the Pacer Pulse Rejection specifications (see
page 100).
Noise on the ECG signal may be detected as pacer signals, causing the pacer indicator to appear on the display. If you
don't need to indicate pacemaker signals, turn off the pacemaker indicator for a better ECG waveform display.
