Resumption of atrioventricular conduction by levosimendan after radiofrequency ablation of the AV node:

Abstract

We report the case of a patient in whom radiofrequency catheter ablation of the AV node was initially successfully performed for persistent atrial fibrillation with fast ventricular rate, but in whom atrioventricular conduction transiently resumes following therapy with levosimendan. Plausible hypothesis are discussed as well as potential implications.
