It is intended to provide an agent for treating atrial fibrillation, comprising an If current inhibitor as an active ingredient. In the present invention, the means for resolution comprises an agent for treating atrial fibrillation, comprising an If current inhibitor as an active ingredient. In particular, it comprises an agent for treating atrial fibrillation comprising (-)-N-{2-[(R)-3-(6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline-2-carbonyl)piperidino]ethyl}-4-fluorobenzamide monophosphate as an active ingredient. The active ingredient according to the present invention has more preferred properties for use as an agent for treating atrial fibrillation compared to Verapamil (a Ca antagonist) and Atenolol (a beta-blocker) which have been conventionally used as the agents for treating atrial fibrillation.
