Heart rate is not counted. Heart rate is low.
Cause
: The ECG waveform amplitude is below the QRS detection level (0.3mV).
Solution 1 : Change the electrode site, or select a lead with higher QRS amplitude.
Note
: Using 4-electrode or 5-electrode/10-electrode instead of 3-electrode allows more
accurate QRS detection.
Also, if a large amount of noise is interfering, the noise may be erroneously detected as
QRS. It is recommended to change the electrode site and increase the ECG amplitude.
Solution 2 : Increase the waveform size. By increasing the waveform size, small QRS wave will
become detectable. However, noise may be also detected.
Heart rate is not counted, and “Lead OFF” message is displayed.
Cause 1 : The electrode of the displayed lead type is detached, or is not making good electrical
contact with the skin.
Solution :
・
Check the electrode application.
・
Replace the electrode, or check the lead cable.
Artificial pacemaker pulse is not displayed.
Cause 1 : On the ECG setup menu, Not used is selected for the pacemaker use.
Solution : Select Used for the pacemaker use.
Cause 2 : On the ECG setup menu, “Pacemaker Pulse” is set to OFF .
Solution :
Select
ON
for “Pacemaker Pulse”.
The “Pacemaker Error” message is displayed.
Cause
: The pacemaker pulse is detected for 16 pulses or more per second.
Solution 1 : Attach the electrodes firmly.
・
Replace the lead cable if defective.
・
If any noise source is near the patient, locate it away from the patient as much as
possible.

Solution 2 : If the patient is not wearing a pacemaker, select Not used for the pacemaker use in
the ECG setup menu.

The “ECG not connected” message is displayed.
Cause
: When the ECG relay cable is disconnected during ECG monitoring, this message will be
displayed.
Solution 1 : To silence the alarm, press the
(Alarm Silence) key.
Solution 2 : To continue monitoring, plug in the ECG relay cable. This will clear the message and
silence the alarm.
