Incidental conversion to sinus rhythm from atrial fibrillation during external jugular venous catheterization

External jugular venous (EJV) catheterization is a frequent method of gaining central venous access because of its low complication rate. We describe a unique experience during EJV in which a patient with chronic atrial fibrillation converted suddenly to a sustained sinus rhythm without perioperative complication from this event. Our experience depicts a rare consequence of the central catheter placement and we, as anesthesiologists, should be aware of its potential occurrence in the operating room.
