8.5.9 Enabling Smart Lead Off
When the smart lead off function is set on and there is a “lead off” in the lead that has an ECG waveform in filter mode
and notch status, if another lead is available, this available lead automatically becomes that lead. The system will
re-calculate HR and analyze and detect arrhythmia. When the “lead off” condition is corrected, the leads are
automatically switched back.
To switch on/off the smart lead off function, select [Others >>] from the [ECG Setup] menu; select [Smart Lead Off] and
toggle between [On] and [Off] from the popup menu.
8.5.10 Setting the Alarm Level for ECG Lead Off Alarms
Select [Alarm Setup >>] from the [User Maintenance] menu. You can set [ECGLeadOff Lev.] from the popup menu.
8.5.11 Adjusting QRS Volume
QRS sounds are produced based on the alarm source. To adjust the QRS volume, select [Others >>] from the [ECG Setup]
menu; select [QRS Volume] from the popup menu and select the appropriate setting. When a valid SpO
2
measured
value is available, the system will adjust the pitch tone of QRS sound based on the SpO
2
value.
8.5.12 About the Defibrillator Synchronization
If a defibrillator is connected, a defibrillator synchronization pulse (100 ms, +5V) is outputted through the
Multifunctional Connector every time the monitor detects an R-wave.
WARNING
 Improper use of a defibrillator may cause injury to the patient. The user should determine whether to
perform defibrillation or not according to the patient’s condition.
 Before defibrillation, the user must ensure both defibrillator and monitor have passed the system test and
can be safely used jointly.
 Before defibrillation, make sure that the [Filter] is set to [Diagnostic].
 After defibrillation is finished, select the filter mode as required.
8.6 About ST Monitoring
 ST segment analysis calculates ST segment elevations and depressions for individual leads and then displays them
as numerics in the ST1 and ST2 areas.
 A positive value indicates ST segment elevation; a negative value indicates ST segment depression.
 Measurement unit of the ST segment: mV or mm. You can set the unit in the [Unit Setup] menu from the [User
Maintenance] menu.
 Measurement range of the ST segment: -2.0 mV to +2.0 mV.
