A novel algorithm for Fitbit wearables using photoplethysmogram (PPG) software was able to detect undiagnosed atrial fibrillation (AF) with a high positive predictive value in a large population study. Another study demonstrated that individual AF trigger testing did not lead to improved AF-related quality of life compared with symptom surveillance alone. However, fewer AF episodes were reported in the experimental arm of the study. Moreover, a significant association was observed between alcohol use and the occurrence of AF. Dr Steven Lubitz (Massachusetts General Hospital, MA, USA) explained that early detection of AF may prevent morbidity of this condition [1]. Since smartwatches and fitness trackers are often equipped with optical PPG sensors, software algorithms that analyse PPG data can detect AF on these wearable devices. Dr Lubitz and colleagues developed a software algorithm with overlapping PPG pulse tachogram sampling and assess...
