Abstract:

BACKGROUND: Atrial fibrillation is the most commonly encountered arrhythmia. Several antiarrhythmic agents are effective in restoring and maintaining sinus rhythm.

AIM OF THE WORK: To compare the efficacy and rapidity of conversion of recent onset atrial fibrillation using oral propafenone versus intravenous infusion of amiodarone.

METHODS: The study included 200 patients with recent onset atrial fibrillation. Patients were equally divided into 2 groups; group A where intravenous infusion amiodarone was given and group B where oral propafenone was administrated. The effectiveness and the time needed for conversion of atrial fibrillation to sinus rhythm were compared in both groups.

RESULTS: The success of conversion of atrial fibrillation to sinus rhythm was 83% in group A and 85% in group B, p-value = 0.699. The time elapsed from drug administration till conversion of atrial fibrillation was 9.07 ± 5.04 hours in group A versus 3.9 ± 1.54 hours in group B, p-value = 0.001. In both groups, patients who showed failed conversion had a significantly larger left atrial diameter and a significantly higher high sensitivity C-reactive protein (hsCRP) level.

CONCLUSION: Oral propafenone was faster than parenteral amiodarone in the conversion of recent onset atrial fibrillation to sinus rhythm. Patients with failed conversion had a bigger left atrial diameter and a higher hsCRP when compared to patients with successful conversion.
