Correct answer: B — Anticoagulate for at least 4 weeks after cardioversion

Regardless of preprocedural strategy, patients undergoing cardioversion require therapeutic anticoagulation for at least 4 weeks afterward due to thromboembolism risk. Antiplatelet monotherapy or procedure-only heparin is inadequate.
