Q

For AF if you cardiovert someone successfully what do you do with the aticoagulation

A

Following elective DC cardioversion, in patients at high risk of stroke, anticoagulation should be continued long-term, even if they remain in sinus rhythm. Therefore, the correct answer is continue anticoagulation lifelong. This would need to be regularly evaluated against bleeding risk.
