ECG 7-1 
7  ECG 
The system can be configured with the optional physio module. In that case, the ECG signal 
is displayed on the image, and can be reviewed simultaneously with the image. 
  When the system is connected with the ECG module: 
  The Physio menu is available. 
  The ECG icon including heart-shaped symbol and heart rate symbol are displayed on 
the screen. 
  The system supports ECG signal from ECG lead or external ECG signal devices. 
  Use DC-IN to connect to the external ECG signal devices. 
WARNING: 
DO NOT use the physiological traces for diagnosis and 
monitoring. 
To avoid electric shock, the following checks shall be 
performed prior to an operation: 
The ECG electrode cable shall not be cracked, frayed or 
show any signs of damage or strain. 
The ECG electrode cable shall be correctly connected. 
You should use the ECG leads provided with the ECG 
module. Otherwise it may result in electric shock. 
The ECG electrode cable must be connected to the system 
first. Only after the cable is connected to the system, can the 
patient be connected to the ECG electrodes. Failure to follow 
these instructions may subject the patient to electric shock. 
DO NOT place the ECG electrodes directly in contact the 
patient’s heart; otherwise it may lead to stop of the patient’s 
heartbeat. 
DO NOT apply the ECG electrodes if the voltage exceeds 15 
volts. This could produce an electric shock. 
Before using high frequency electric surgical unit, high 
frequency therapeutic equipment or defibrillator, be sure to 
remove the ECG electrode from the patient, in order to 
prevent electric shock. 
Conductive parts of electrodes and associated connectors 
for ECG should not contact other conductive parts including 
earth/grounding. 
Frequent trampling or squeezing on the cables may result in 
cable break-down or fracture. 
 
When abnormality is detected, please check if ECG leads are properly connected 
with the system.
