122 Stratos LV/LV-T Technical Manual

A total of 64 recordings can be stored. Each of the four triggering types of recording can be assigned a specific number (i.e., X out of 64). When a newly saved recording exceeds the programmed number of recordings per event, the oldest recording is deleted. An exception is the first recording and those with the longest duration for each event. These are not over-written.

NOTE:

The total length of each recording can be up to 10 seconds. While the associated marker chain is always 10 seconds long, the associated IEGM can be shorter depending on the amplitude and rate since the rate and amplitude influence the amount of data to be saved.

In Snap-Shot Pretrigger, it is possible to define the percentage of the recordings before the trigger event.

In addition, it is possible to make a recording at the end of the tachycardia (criterion for deactivation) of the respective event (exception: patient-triggered recordings that do not last).

At the next follow-up examination, the programmer automatically notes the recordings that have been made. When interrogated, the recording appears on the screen.

Note: If the recording has been triggered by the patient (by placing a magnet over the pacemaker), make sure that the synchronous magnet effect is selected.

CAUTION

IEGM – Due to the compression processes that the signals undergo, the IEGM recordings are not suitable for making some specific cardiac diagnoses, such as ischemia; although, these tracings may be useful in diagnosing arrhythmias, device behavior or programming issues.

If the “patient-triggered recording function has been activated, please instruct the patient on how to use the magnet to trigger an IEGM recording.
