Abstract

Aim—To determine whether elective direct current (dc) cardioversion of atrial fibrillation/flutter causes myocardial damage.
Methods and results—Cardiac troponin T and creatine kinase were estimated 20-28 hours after dc cardioversion in 51 patients who received dc shocks for elective cardioversion of chronic atrial fibrillation/flutter. Although creatine kinase was raised in 44 patients, cardiac troponin T was undetectable in all patients.
Conclusion—Cardiac damage does not occur as a result of cardioversion.

 Keywords: cardioversion;  troponin T;  creatine kinase;  atrial fibrillation
