Fitbit has been given the green light: its devices will be able to detect atrial fibrillation (AFib). The ok comes from the United States and the European Union, where the respective bodies in charge have given authorization for the detection through the ECG app which made its debut at the end of August on the new Sense. The function will be available in some countries (including Italy) starting from October initially on the Sense.
Atrial fibrillation is a widespread disorder all over the world – there are more than 30 million people affected – and it is not easy to identify, as it can have no symptoms, hiding its danger. A 2016 study estimated that about one in four people find they suffer from AFib only after they have had a heart attack. Fitbit intends to provide its users with a measurement tool to share data with their doctor: the algorithm has been tested in the United States and is particularly accurate: in fact, 98.7% of atrial fibrillation cases and 100 % of those with normal sinus rhythm.
The study was conducted by Fitbit in May on a sample of American users over the age of 22, highlighting the correct functioning of the photoplethysmographic technology adopted for the detection. This tool is particularly useful now that the social distancing imposed by the pandemic is forcing a large number of people to avoid traveling from home, limiting them only to those deemed essential. In short, a pre-measurement at home via the ECG app can be really important, to be shared with your doctor anyway if anomalies should be highlighted.
The measurement is simple: just open the ECG app on your Sense and place your fingers on the steel edge of the smartwatch for 30 seconds. The data can then be viewed on the smartphone or directly on the smartwatch to be shared later with your doctor.
