Direct current cardioversion does not cause cardiac damage: evidence from cardiac troponin T estimation.
نویسندگان
چکیده
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.

Cardiac troponin T does not increase after electrical cardioversion for atrial fibrillation or atrial flutter.
OBJECTIVE To determine whether cardiac troponin T increases after electrical cardioversion in patients with atrial fibrillation or atrial flutter. DESIGN Serum creatine kinase (CK), creatine kinase-MB (CKMB), and cardiac troponin T were measured before, 24 hours, and 48 hours after cardioversion in 15 patients with atrial fibrillation or atrial flutter. RESULTS 12 of the 15 patients (80%) w...
متن کاملCardiac troponin I levels are normal or minimally elevated after transthoracic cardioversion.
OBJECTIVES The present study was designed to assess the impact of direct current shocks on cardiac troponin I (cTnI), which has greater sensitivity and specificity than creatine kinase (CK) for the diagnosis of myocardial injury. BACKGROUND Transthoracic direct current shocks can cause myocardial injury. They also cause elevations of total CK and CK-MB fraction (CK-MB). METHODS We obtained ...
متن کاملCardiac troponin T and cardiac enzymes after external transthoracic cardioversion of ventricular arrhythmias in patients with coronary artery disease.
BACKGROUND Serum levels of cardiac troponins after external cardioversion (ECV) for atrial fibrillation and atrial flutter are widely investigated, and no increases in cardiac troponin T (cTnT) levels have been reported. However, the effect of ECV on cardiac enzyme release may depend on the type of arrhythmias. Furthermore, ventricular tachycardia (VT) or ventricular fibrillation (VF) could cau...

INTRODUCTION AND OBJECTIVES In this study we measured the concentrations of cardiac troponin I (cTnI) and several biochemical markers of myocardial damage after elective external cardioversion or internal cardioversion by specific catheters or automatic defibrillators. MATERIAL AND METHODS Biochemical markers were analyzed prospectively for 30 consecutive patients after electrical cardioversi...
متن کاملEffect of topic defibrillation on serum markers of myocardial damage.
Serum levels of cardiac enzymes and troponins after external cardioversion (ECV) for atrial defibrillation and atrial flutter, and after endocardiac cardioverter defibrillation by implantable cardioverter defibrillator (ICD), have been well investigated. The aim of this study was to assess the effects of topic defibrillation (TD), after cardiac surgery, on cardiac enzymes in patients with uncom...
