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.
