G. Neumayr et al., PLASMA-LEVELS OF TROPONIN-T AFTER ELECTRICAL CARDIOVERSION OF ATRIAL-FIBRILLATION AND FLUTTER, The American journal of cardiology, 80(10), 1997, pp. 1367
To establish possible myocardial damage by direct-current countershock
, we measured plasma levels of troponin T after electrical cardioversi
on in 33 nonselected patients with atrial fibrillation or flutter. Unc
hanged normal levels of troponin T indicate that significant myocardia
l cell injury by shocks in the usual dosage is unlikely to occur.
