ECG
or electrode placement which causes the pacemaker pulse amplitude to decrease and
disables the pacemaker pulse detection.
If signals similar to a pacemaker pulse are present, such as electric blanket noise or
excessive AC frequency noise, these may be erroneously detected and displayed as
a pacemaker pulse.
When a spontaneous QRS and pacemaker pulse overlap (ex. fusion beat, etc.), QRS
detection cannot be performed properly. In this case, the heart rate is degraded.
If a pacemaker pulse is continuously detected due to AC frequency interference, QRS
detection will be suspended and the heart rate will be reduced. Arrhythmia will not be
detected either.
[ON]/[Distinct Color]: Displays the artificial pace pulse in yellow.
[OFF]: The pacemaker artificial pulse will not be displayed.
"Pacemaker Pulse" will be automatically set to [ON] when [Used] is selected for "Pacemaker" on the
"Admit/Discharge" screen.

Pace Pulse Mask Time
WARNING
If the QRS pace mask function is set to [OFF]/ [10ms]/ [20ms]/ [40ms], the pace pulse
may be erroneously be detected as a QRS complex and HR, asystole alarms may not
generate due to incorrect HR (counting pace pulse as QRS complex). Select [OFF]/
[10ms]/ [20ms]/ [40ms] only if you are sure that pacing failure will not occur, or when the
patient can be constantly monitored.
REFERENCE
For the patients using pacemakers, there are cases when the pacing waveform may not
occur in spite of the pacing stimulus. This condition is called "pacing failure".To avoid
detecting pacemaker pulses as a QRS complex, this monitor has a function to suspend
QRS detection for a fixed amount of time starting from the detection of the pacing
stimulus. This function is called "pace pulse mask" .
But if the pacemaker does not detect the patient's spontaneous heartbeat (sensing
failure), and the pacing stimulus is applied at the same timing as QRS, this pace mask
function may erroneously mask the QRS and cause the heart rate measurement to
decrease.
To avoid this, QRS pace pulse mask function can be set to [OFF]/ [10ms]/ [20ms] for
correct measurement of the heart rate.
