Fitness trackers are helpful little gadgets for anyone looking to get in shape, but it turns out they may be more useful than we realize. As one woman in Connecticut found out recently, wearing a Fitbit could just save your life.
According to CNN, 73-year-old Patricia Lauder became concerned when she noticed her Fitbit was displaying an alarmingly high resting heart rate. She'd been in and out of the doctor's office while battling a sinus infection and was waiting on some test results, but decided to call 911 when her heart rate skyrocketed to over 100 beats per minute.
Because of the data her Fitbit had saved, Lauder knew that her normal resting heart rate was between 60 and 70 beats per minute, so seeing it display 140 beats per minute was very concerning.
