Pacemaker battery life
My grandson had a pacemaker check in mid-February and was told he had 9 months of battery life plus the 3 month ERI time (total 12 months). They were looking at a pacemaker replacement toward the end of the year. We were doing 3 month pacemaker checks, until August, then going to monthly until time for the replacement. We did a remote check in mid-May and was told the pacer went into the ERI time on April 10th, therefore he was already almost 2 months into the ERI. What would make a pacemaker battery lose that much battery in so little time?
