Dan's Fitbit A-fib heart scare

Dan tells his heart story: after yard work, his Fitbit told him his heart was in A-fib — twice, with no symptoms at all. His daughter, who works in the medical field, sent him to the hospital, where he was put on a blood thinner and, after four days, had a fifteen-minute cardioversion procedure to shock everything back into rhythm. He reports no damage and no life changes, calling himself rescued by the Fitbit.
