Several advances have been made in antiarrhythmic medications, including the development of ibutilide, a class III antiarrhythmic drug indicated for acute cardioversion of atrial fibrillation.

Pharmacologic cardioversion, although less effective, offers an alternative to DC cardioversion. Drip rate (Drops per minute 60) / Drop factor. However, the drip rate can also be calculated using the drop rate formula (this function is available in the advanced mode of our gtt in min calculator): Drip rate Drops per hour / Drop factor, or. External direct current (DC) cardioversion is the most effective means of converting atrial fibrillation to sinus rhythm. Drip rate (mL/hour) Total volume (mL) / Infusion time. Although many patients with atrial fibrillation experience relief of symptoms with control of the heart rate, some patients require restoration of sinus rhythm. Atrial fibrillation is the most common arrhythmia in patients visiting a primary care practice.
