I just want to ask if there are any other reasons for replacement besides low battery?
Usually it's low battery. Recalls are rare but they happen and sometimes that means early replacement. If a lead went bad sometimes they'd give a new box when they fix the lead. Upgrading to a 3 lead or ICD.
Beside low battery I have had to have a replacement cause of a recall and also cause of my leads failed. Had it since I was 17 and have had 5 replacements.
I had number four replaced early to get number five. "upgraded" from a dual chamber to a three chamber (biventrical).
Basically battery is the reason why they get replaced, with rare exceptions.

I wouldn't be alive if it wasn't for pacemakers. I've had mine for 35+ years. I was fainting all of the time and had flat-lined also. I feel very blessed to live in this time of technology.
