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

•

Low

P-Wave

Amplitude*)

 

< 300 and > 3000 Ohm

 

(<50% safety margin)

•

Ventricular Lead

Check

•

Low

R-Wave

Amplitude*

 

< 300 and > 3000 Ohm

 

(<50% safety margin)

•

ACC Disabled

 

•

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.
