[Everyone over the age of 65 years should wear a smartwatch : Pro and contra].

Atrial fibrillation (AF) is one of the most common cardiac arrhythmias and has far-reaching consequences not only for patients, but also for our healthcare system. The prevalence of this condition is expected to double in the coming decades. On the one hand, this is due to our aging population, the increasing number of comorbidities, and the improved technical possibilities for detection. A major complication of AF is stroke, whereby at-risk patients can be protected by oral anticoagulation if AF is diagnosed. The extent to which continuous screening for AF in patients with an increased risk of thromboembolic events should be carried out using wearables remains an important point in the current debate.
