What began as a fun technological gift at Christmas ended up helping to detect the health problem of a Nashua man.
Barry Maden thought he was only anxious to travel during the holidays, but his new Apple Watch alerted him that it was something much more serious.
The self-styled "tech geek" said he bought the watch partly to monitor his health after suffering a brain injury.
"He originally got it because they have a new fall risk application where, if he fell and I was not around, the fall sensor will feel like he fell and called 911," said his wife, Tara Maden.
But the new clock actually ended up detecting something that Maden did not even have on his radar.
"And he said:" It looks like your heart is in AFIB, you should contact your doctor, "Maden said.
Atrial fibrillation, or AFIB, is an irregular heartbeat. If left untreated or not detected, AFIB can cause blood clots and cause a stroke or other cardiac complications.
With the clock showing Maden how his real beats looked, he decided to go to a hospital.
"When I arrived at the emergency room, they made a real EKG on a cart, the real one," he said.
Indeed, medical professionals told Maden that, in fact, he was at AFIB.
"It would probably have taken me longer if I had not had something to tell me that something is not right," he said.
Maden was sedated, and his heart was essentially stopped and reinitiated by scholars.
Now, the small piece of technology seems an even greater gift to the Madens.
"Instead of being just a toy or a tchotchke, I think I'll probably pay more attention to it," said Maden.
