Smart devices for a smart detection of atrial fibrillation

Atrial fibrillation (AF) is the most frequent sustained cardiac arrhythmia and is associated with significant clinical events and costs. A higher and increasing prevalence of AF has been reported, mostly due to advances in diagnosis methods (1). AF morbidity and mortality reports are based primarily on symptomatic AF. However, in at least one third of patients, AF is neither clearly symptomatic nor noticeable due to degradation of functional class.
