The duration and frequency of episodes of atrial fibrillation (AF) and the longitudinal history of this arrhythmia can vary markedly across patients. The currently accepted scheme for AF classification is based on temporal rhythm-based patterns. In this Review, the authors discuss the advantages and limitations of this categorization, highlighting gaps in knowledge that are opportunities to re-examine the current scheme and may lead to future improvements in AF classification.
