Deanna Recktenwald was sitting in church next to her mum one Sunday when she looked down at the Apple Watch she got for Christmas.
It told the 18-year-old her resting heart rate was between 120 and 130 beats per minute, even though she was sitting perfectly still.
60 to 100 is considered a normal rate.
When her resting heart rate reached 190, the watch told the Florida teenager to seek medical attention. She told her mum Stacey, a registered nurse, who didn’t trust her daughter’s heart rate could be so high.
“She checked my pulse with her fingers and it was spot on every time she checked,” Deanna told ABC Action News.
Stacey added, “It was alarming that the watch was telling us to seek medical attention. I didn’t even know that it had the capability of giving us that alert.”

Deanna had been experiencing some shortness of breath prior to her watch’s warning. But she was “a fit, athletic kid,” her mum said.
By the time Deanna was admitted to Tampa General Hospital, staff noticed her heart rate was coming back down. But they took blood and ran a series of tests just in case.
“The blood work came back showing my kidneys were failing,” Deanna told InsideEdition.com.
“It was a complete shock… I was in kidney and liver failure four years ago, but that was due to an infection that spread to my whole body.”
Doctors found Deanna had chronic kidney failure, her kidneys were functioning at only 20 per cent capacity.
“The prognosis isn’t good — she’s going to need a kidney transplant in two to three years,” Stacey said.
