The RITHMI study: diagnostic ability of a heart rhythm monitor for automatic detection of atrial fibrillation.

Introduction And Objectives: Early detection of atrial fibrillation (AF) is a priority to reduce embolic events by initiating oral anticoagulation therapy. The aim of this study was to evaluate the diagnostic ability of a wrist device designed for automatic AF detection.

Methods: RITHMI is a prospective, comparative, observational study that included 167 patients referred to a cardiology outpatient clinic for a general consultation or for electrical cardioversion.
