Version 2.2.0 

Possible solutions "ECG no signal": 

•

  Verify that ECG cables are firmly connected to buttons. 

•

  Check the display of the synchronization device—is it generating a synchronization 

signal on each R-wave?  Toggle different lead combinations on the synchronization 
device until a satisfactory synchronization signal is found. 

•

  Relocate ECG buttons on patient and try lead combinations again. 

After the 3.5 seconds and BEFORE delivering a test pulse, if the ECG signal is fast, the 
button for 

Deliver test pulse

 will be inactive and the Run section of the screen in Figure 6-3 

will display:  

 

"External ECG trigger noisy. Please check the connection." 

     

  

Figure 6-3: Run Section with ECG Noisy on Pulse Generation Screen Before Test Pulse 

 

Possible Solutions for "ECG Noisy." 

•

  Check for ECG double counting.  Select a different lead on the synchronization 

device. 

•

  Check for a noisy ECG signal.  Verify cable connections and buttons are secure.  

Noise may come from RF energy devices connected to the patient (e.g., 
electrocautery) or from high-energy devices (x-ray equipment, etc.) on the same 
circuit. 

If the ECG signal is synchronized DURING delivery of the test pulse, the Run section of the 
screen in Figure 6-4 will display:
