Biochem/physiol Actions
Ibutilide hemifumarate salt is considered a new generation "pure" Class III antiarrhythmic agent.
Ibutilide hemifumarate salt is considered a new generation "pure" Class III antiarrhythmic agent. Ibutilide binds to and alters the activity of hERG potassium channels, delayed inward rectifier potassium (IKr) channels and L-type (dihydropyridine sensitive) calcium channels.

Ibutilide has been commonly used for pharmacologic cardioversion of atrial fibrillation and flutter in clinical settings. The objective of this study was to investigate the effects of ibutilide on the defibrillation threshold (DFT), restitution properties, dispersion of refractoriness and activation

While able to achieve clinical success, the current step-wise approach to persistent atrial fibrillation (AF) ablation requires considerable "substrate" ablation and frequently mandates multiple procedures to address consequent atrial tachycardias (ATs). An alternative strategy minimizing the amount of ablation while

Beyond pulmonary vein isolation (PVI), adjuvant ablation at the sites of complex fractionated atrial electrograms (CFAE) has been shown to improve the long-term success of catheter ablation of persistent atrial fibrillation (AF). However, this approach often requires extensive ablation due

The effects of ibutilide on non-isthmus-dependent atrial flutter (NIDAFL) and the left atrium are not completely known. We describe a case report of 2:1 left to right interatrial block as a result of ibutilide during NIDAFL. This is a 68-year-old

Chinese medical journal, 124(5), 710-713 (2011-04-27)
Patients with persistent or permanent atrial fibrillation (AF) often need direct current cardioversion after radiofrequency ablation. The aim of this study was to investigate the effectiveness and safety of ibutilide for cardioversion of persistent or permanent atrial fibrillation after radiofrequency
