The length of the time interval (monitoring interval) is preset to 
“daily”.  For each monitoring interval, a data set is generated in 
the implant and the transmission is initiated at the designated 
time. 
2.17.4.2 Event Report 
When certain cardiac and technical events are detected by the 
implant, a report transmission is automatically triggered.  This is 
described as an “event message”. 
The following cardiac and technical events initiate a message 
transmission: 
• Atrial  Lead  Check 
< 300 and > 3000 Ohm 
•  Ventricular Lead Check 
< 300 and > 3000 Ohm 
• ACC 
Disabled 
• Low P-Wave Amplitude*) 
(<50% safety margin) 
• Low R-Wave Amplitude* 
(<50% safety margin) 
•  Ventricular Threshold >4.8V

AUTION
 
Event Triggered Report - A timely receipt of the event report 
cannot be guaranteed.  The receipt is also dependent on 
whether the patient was physically situated in the required 
coverage range of the patient device at the time the event 
information was sent. 
 
                                                      
 
*) 
Examples: The programmed sensitivity is 1.0 mV. 
A) Average of the measured P/R-Wave amplitudes is 2.6 mV.  Therefore, 
measured value is greater than 100% of the safety margin.  Event report is 
not triggered. 
B) Average of the measured P/R-Wave amplitudes is 1.9 mV.  Therefore, 
measured value is less than 100%, but greater than 50% of the safety 
margin.  Event report is not triggered. 
C) Average of the measured P/R-Wave amplitudes is 1.4 mV.  Therefore, 
measured value is smaller than 50% of the safety margin.  As a result, an 
event report is triggered.
