I have a unique situation. Had an internal monitor put in in 2017, my heart stopped, so I was scheduled for a pacemaker at which time the monitor was supposed to be removed. I was half awake during procedure and cardiologist dropped the monitor and could not retrieve at that time it was in my chest after lots of denials and no mention on the surgery report, the monitor started moving (no pain and felt no movement) eventually monitor made its way to my breast, where it made a 180 degree turn last year. My main concern is the battery, it has now been almost 3 years, since it is a 2 year monitor I don't suppose the battery life is too long. Monitor is deep in the tissue and surgeons are reluctant to "poke around for it" their words. I maybe worrying needlessly just would rather not have an acid leak in my breast.
