Aside from patient factors, a number of factors may influence the immediate success of cardioversion, that is, a complete failure to cardiovert. These include electrode placement, shock polarity ...

Likewise, the larger the left atrium, the less likely that sinus rhythm can be maintained after cardioversion, especially without antiarrhythmic drugs. Physiological atrioventricular (AV ...

Background: Several clinical factors have been studied to predict atrial fibrillation (AF) recurrence after electrical cardioversion (ECV) with limited predictive value. Methods: A method able to ...

The medical treatment is procainamide, although electrical cardioversion is reasonable, especially if hemodynamically unstable. In patients with WPW and atrial fibrillation, the erratic atrial ...

Administration of antiarrhythmic drugs is considered in cases of refractory VF/pulseless VT—that is, when cardioversion does not occur after 12 DC shocks with appropriate advanced life support ...
