New Jersey doctors say wearing a Fitbit saved one man's life.

A man came into an emergency room after having a seizure and was unaware his heart was beating irregularly when doctors asked him about it, NPR reports.

The doctors were able to look up the heart rate data on his Fitbit to see when the irregularity started. If the heartbeat had changed for more than 48 hours, then resetting the heart had a high risk of clot, according to NPR.

The patient's heartbeat had changed only two hours before his visit, and doctors were able to help him. While doctors note that a Fitbit is not a medical device, the information gathered can be helpful, NPR reports.

The findings were published in Annals of Emergency Medicine journal.
