A quick internet search fails to find anything in support of what you say.
That’s always possible.
Maybe I misunderstood.
This is all I found:
“Nancy Guthrie’s pacemaker stopped syncing with her Apple devices around the time she was believed to be abducted, but it is unclear if it is working again. The pacemaker’s spike in activity could indicate she was involved in a struggle, but further details about its current status have not been disclosed.”
