6.4.2.3 EGM storage changes
When at least 1 High Rate-NS episode occurs, the device automatically adjusts EGM
storage operation in order to provide more diagnostic data to help identify a lead-related
issue. The device programs the Pre-arrhythmia EGM parameter to On - 1 month (unless
the previous setting provided more than 30 days of Pre-arrhythmia EGM storage remaining).
Notes:
●
The Pre-arrhythmia EGM parameter will display the programmed setting even when the
device automatically adjusts EGM storage after a High Rate-NS episode has occurred.
●
The changes to EGM storage occur even when the Device Tone and Patient Home
Monitor alert parameters for RV Lead Integrity Alert are programmed to Off.
If the Lead Impedance and Sensing Integrity Counter criteria are met, the device also
changes the criteria for storing High Rate-NS episodes, allowing a High Rate-NS episode
with EGM data to be recorded if a single ventricular interval less than 200 ms occurs. This
condition persists until a High Rate-NS episode occurs or until the device is interrogated by
a programmer.
6.4.3 Programming considerations for RV Lead Integrity Alert
VF Detection and VF therapies – If you program VF Detection or all of the VF therapies
to Off, the RV Lead Integrity Alert does not operate. The RV Lead Integrity Alert operation
resumes when you program VF Detection and the VF therapies to On, and only the data
collected after that time are applied to the alert criteria.
