Fitbit has some of the most compelling features when it comes to checking in on your overall health and wellness, not just activities, daily steps, heart rate, and calorie burns. One of the most compelling new features you'll find in many of the brand's newest smartwatches and fitness trackers is the ability to check for Atrial fibrillation (Afib), an irregular heart rhythm. 

Once set up, you'll receive irregular heart rhythm notifications should the device detect an irregular heartbeat, at which point you can keep a log to discuss with your doctor at the next visit or contact a medical health professional for advice if it's cause for concern. You'll also be advised if no irregular heart rhythm was detected. While the data is not intended for diagnostic purposes, it can give you a good indication of your heart rate and pulse rhythm so you can seek further assistance if needed.

What else should you know about Fitbit's irregular heart rhythm (AFib) notifications?

It's important to note a few things before you set up your Fitbit to detect irregular heart rhythms. First, note that it is not a medical device nor should you adjust medications or act in any way based on the data without talking to a medical professional. The device should never be used in place of a medical device provided by a doctor or other medical professional.

Second, the feature is not designed to be used for people under the age of 22 nor for people who have a history of atrial fibrillation that has been diagnosed by a doctor or who have a cardiac pacemaker or implantable cardioverter-defribillator. It is merely an added tool to detect unexplained or sudden atrial fibrillation so you can discuss with a doctor if necessary. The idea is that Afib is treatable if it's detected early, and a Fitbit device with this feature can help you do that. It does not detect heart conditions like heart attack, blood clots, or stroke. As always, if you believe you are experiencing a medical emergency, you should contact emergency services.

Note, also, that the irregular heart rhythm (Afib) notifications only work in certain countries and regions right now, which includes the U.S. but does not yet include Canada.
