How do medications treat occasional atrial fibrillation?

Medications used to treat occasional atrial fibrillation are prescribed by doctors to prevent blood clots, control heart rate, and help restore and maintain a heart's natural rhythm. There are three main clot-preventing drugs on the market: warfarin, heparin, and aspirin. These are blood thinning drugs which help to prevent blood clots from forming. In some people, heart rate is controlled using medications such as beta blockers, calcium channel blockers, and digitalis. While these drugs are effective at restoring heart rate to a normal rate, they may not do anything for controlling heart rhythm. But they will almost always make people who take them feel better. When doctors want to restore someone's heart rhythm to a normal one, they generally will prescribe drugs like amiodarone, sotalol, and ibutilide.
