Consumer electronics provide a novel route to screen for atrial arrhythmias. A study offered smartphone and wearable-based continuous arrhythmia screening to older adults without known atrial fibrillation. Atrial arrhythmia was detected in five percent of the participants. The study was performed by AFNET. The principal investigator was Professor Larissa Fabritz, University of Birmingham and University Medical Center Hamburg Eppendorf (UKE), Hamburg, Germany.
