A 66-year-old woman with a past medical history of hypertension undergoes DC cardioversion for atrial fibrillation. Immediately following the procedure, transient ST elevation is seen. The patient is asymptomatic post-procedure but cardiac enzymes are taken 12 hours later. These show a normal troponin I but a raised CK. The SHO calls you to advise him on the significance of the ECG and blood tests.
What do you advise?
Transient ST elevation can be a normal finding post DC cardioversion. A rise in CK is also usually normal but neither troponin T nor troponin I should rise following DC cardioversion of AF.
