Atrial Fibrillation Detection Using RR-Intervals for Application in Photoplethysmographs

no code implementations • 13 Feb 2023 • Georgia Smith, Yishi Wang

Our primary goal is to analyze Atrial Fibrillation data within ECGs to develop a model based only on RR-Intervals, or the length between heart-beats, to create a real time classification model for Atrial Fibrillation to be implemented in common heart-rate monitors on the market today.
