Abstract
To establish possible myocardial damage by direct-current countershock, we measured plasma levels of troponin T after electrical cardioversion in 33 nonselected patients with atrial fibrillation or flutter. Unchanged normal levels of troponin T indicate that significant myocardial cell injury by shocks in the usual dosage is unlikely to occur.
