You were rounding late on a Friday afternoon when you were paged to see a 24-year-old patient with atrial fibrillation (AF) in the ICU. The arrhythmia was secondary to acute respiratory distress syndrome and appropriate management was initiated.
You thought you were on your way home for the weekend when the medical resident who paged you decides that you have been so helpful on this young patient that he wants to “curbside” you on another patient in the ICU.
The patient is a 48-year-old male who was brought to the ICU after a motor vehicle accident and was found to have a normal TSH but upper limits of normal FT4.
The resident asks if this patient is at increased risk for developing AF.
