Nancy Guthrie’s 2 a.m. pacemaker spike on the day she vanished could mean that the elderly woman was involved in a heart rate-raising struggle with her possible captors, a lead cardiologist speculated Thursday.
“If a person was in a physical struggle, that might have created a rapid heartbeat … the pacemaker would have detected that and potentially reported it,” Dr. Jonathan Reiner, who was former Vice President Dick Cheney’s cardiologist, chillingly told CNN.
Arizona authorities previously said the 84-year-old’s implanted medical device stopped syncing with her Apple devices, including a watch and her iPhone, around 2 a.m. Sunday — close to the time police believe she was abducted from her Tucson home.

Nancy was last seen the night before when she was dropped home by her son-in-law at about 9:45 p.m.
When investigators reached the home hours after she was reported missing, around noon, the devices were still in the house.
