The elective replacement indicator (ERI) of an automatic implantable cardioverter-defibrillator (AICD) is intended to be utilized as strict criteria for the appropriate timing of pulse generator replacement. The manufacturer's newest recommendations suggest replacement within 3 months post-ERI attai.. Explant of a device following RRT/ERI within the timeframe recommended reduces the risk for erratic or unanticipated therapies, pacing, loss of pacing, loss of sensing, or other potentially harmful behavior.

ABSTRACT.We report two cases of device malfunction with loss of pacing output during routine device generator replacement surgery after using electrocautery. These devices were nearing or had just reached the elective replacement indicator (ERI). Most current devices are relatively robust during electrocautery, although manufacturers warn of potential damage to the device. Device.. Setting changes at ERI including a change from dual- to single-chamber pacing and/or loss of RR results in a significantly increased symptom burden and increased healthcare utilization.
