.5.13 About the Defibrillator Synchronization
If a defibrillator is connected, a defibrillator synchronization pulse (100 ms, +5V) is outputted through the
multifunctional Connector every time when the patient 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 has passed the system test and
can be safely used jointly.

.6 About ST Monitoring

Mortara ST segment analysis is not intended for neonatal patients.

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.
WARNING

The ST algorithm has been tested for accuracy of the ST segment data. The significance of the ST segment
changes need to be determined by a clinician.

.6.1 Switching ST On and Off
To switch ST monitoring on or off:
1. In the [ ECG Setup ] menu, select [ ST Analysis >> ].
2. Select [ ST Analysis ] to toggle between [ On ] and [ Off ].
Reliable ST monitoring can hardly be ensured if:

You are unable to get a lead that is not noisy.

Arrhythmias such as atrial fib/flutter cause irregular baseline.

The patient is continuously ventricularly paced.

The patient has left bundle branch block.
In these cases, you may consider switching ST monitoring off.
