Programming constraint: Automatic AV delay reduction is limited to
125 ms for rest AV delay and to 80 ms for exercise AV delay.
8. PATIENT FOLLOW-UP
8.1. FOLLOW-UP RECOMMENDATIONS
Standard follow-up: Annual standard follow up is recommended.
Before the patient's discharge, and at each follow-up visit, it is
advisable to: 1. Check the battery status. 2. Check for proper sensing
(sensitivity, crosstalk) and pacing; set the pacing amplitude to twice
the pacing threshold. 3. Interrogate the device memories (AIDA+).
4. Keep a printout of programmed parameters, test results, and
memory data.
Frequent follow-up: It is advisable to follow up the patient every
6 months when the battery impedance becomes greater than or
equal to 5 kilohms, especially for pacing-dependent patients.
Replacement: The pacemaker should be replaced as soon as the
Elective Replacement Indicator (ERI) point is reached.
Implant software upgrade: In case a new implant software is
downloaded in the device memory through the programmer, a
warning message could be displayed by the programmer to inform
the user and give the proper instructions to follow.
8.2. ELECTIVE REPLACEMENT INDICATOR (ERI)
The Elective Replacement Indicator (ERI) is controlled by:
-1
a magnet rate 80 ± 1 min
battery impedance of 10 kilohms
Caution: The pacemaker should be replaced as soon as the Elective
Replacement Indicator (ERI) point is reached.
