Use of Fish Oils to Reduce Recurrence of Atrial Fibrillation Following DC Cardioversion

Use of Fish Oils to Reduce Recurrence of Atrial Fibrillation Following DC Cardioversion.

The purpose of this study is to investigate whether fish oil supplements may be beneficial in preventing the recurrence of atrial fibrillation after cardioversion.

Atrial fibrillation is a heart condition which can sometimes be successfully treated by a cardioversion.

Cardioversion involves resetting the heart back to normal with the use of electric current.

There is a tendency for the atrial fibrillation to recur , days weeks or even months after the cardioversion.
