Conversion of Persistent Atrial Fibrillation After Radiofrequency Ablation by Ibutilide

Journal of Atrial Fibrillation

Abstract

Ablation of peristent AF remains challenging with questions unanswered about what the ideal next step after pulmonary venous isolation should be. Ibutilide is a highly effective class III agent for cardioversion of acute-onset atrial flutter and fibrillation, with limited clinical use due to risks of ventricular pro-arrhythmias. However, results from the on-going MAGIC-AF trial may re-invigorate its role in clinical electrophysiology as an invaluable adjunct to facilitate controlled substrate modification during ablation of persistent AF.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
