IEGM Recordings
Purpose
This function makes it possible to automatically record the progression
of intracardiac events. These recordings are made between follow-ups
and provide diagnostic information about the origin of the tachycardia,
especially the time just prior to a tachycardia episode.
Description
When the preset criteria are satisfied, the IEGM recordings are
automatically started and data are recorded for up to 10 seconds. The
recordings can be shorter if the rates and amplitudes are high.
A maximum of 20 IEGM recordings is possible, and each recording
type can be assigned a specific number according to the memory
management priorities.
Optimized Memory Management
The IEGM recordings are saved in the order that they occur until all
memories are full. With this principle, these IEGM recordings are not
overwritten, and thus not deleted:
• The last 3 patient IEGMs that were activated by magnet application
• 4 IEGMs for the atrial rate or mode switching:
— The oldest, longest, most recent recording for the atrial rate and
highest ventricular value recorded
• 3 IEGMs for high ventricular rates:
— The longest, highest, and most recent recording
