106 Stratos LV/LV-T Technical Manual
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
CAUTION
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.
