PCP notes describe the presence of atrial fibrillation for 10 days.

Atrial fibrillation (AF) type is determined largely by episode duration and whether the rhythm self-terminates. In outpatient CDI education,paroxysmal AFis intermittent and typically terminates spontaneously, commonly within7 days(often within 48 hours).Persistent AFis sustained and lastsmore than 7 days, or requires active intervention (e.g., cardioversion) to restore sinus rhythm. This scenario documents AF “for10 days,” which exceeds the 7-day threshold and therefore best fitspersistentAF. The management also aligns with a sustained arrhythmia strategy: rate control (atenolol), rhythm control/antiarrhythmic therapy (sotalol), stroke prevention anticoagulation (rivaroxaban), and discussion of catheter ablation, which is often considered for symptomatic or recurrent/persistent AF. “Chronic” is a nonspecific descriptor and not the preferred current classification term, andpermanent AFimplies a decision has been made not to pursue rhythm control (accepting AF long-term), which is not supported here because rhythm-control options are being considered.
