NOTE: [PACE MAKER] switch
1. When a patient with a cardiac pacemaker is examined, the pacing pulses
generated by the pacemaker may be incorrectly recognized as the R-wave
signals, and as a result, ECG gating or heart rate counting may not be
performed correctly.
When the [PACE MAKER] switch is set to ON, the pacing pulses and
R-wave signals can be distinguished, allowing ECG gating and heart rate
counting to be performed based on the R-wave signals. However, even
when the
[PACE MAKER] switch is set to ON, ECG gating or heart rate
counting may be performed based on the pacing pulses depending on the
particular pacemaker or patient.
Diagnosis should be performed based on a comprehensive assessment of
all available information, including the displayed waveforms.
2. When examining a patient with strong R waves, the system may
mistakenly recognize these R waves as pacing pulses. If this is the case,
set the
[PACE MAKER] switch to OFF.
No. Menu Function
<1> Used to turn the ECG waveform display ON/OFF.
<2> Used to turn the PCG waveform display ON/OFF.
<3> Used to turn the display of signals from external devices
ON/OFF.
<4> Used to avoid incorrect R-wave trigger detection due to
the pacing pulses generated by a cardiac pacemaker
(when examining patients with cardiac pacemakers).
<5> Used to invert the ECG waveform. This switch is
effective only in Real-time display mode.
<6> Used to turn the respiratory signal display ON/OFF.
<7> Used to turn the pulse signal display ON/OFF.
<8> [MANUAL] : The gain of ECG, AUX, PULSE, RESP, or
PCG (<16> to <20>) is adjusted
individually.
[AUTO] : The gains of these signals are all adjusted
at the same time.
The
[ECG GAIN] switch changes to
[AUTO GAIN] , and the [PCG Gain] ,
[RESP Gain] , [Pulse Gain] , and [AUX
Gain] switches are disabled.
<9> Used to reset the ECG waveform to the reference
position when the ECG waveform is disturbed.
<10> Used to adjust the baseline position of the ECG
waveform.
