心房細動
Rotigaptide is being studied for its antiarrhythmic effects, specifically for treating atrial fibrillation. Atrial fibrillation is an irregular and often rapid heart rhythm. The irregular rhythm, results from abnormal electrical impulses in the heart. The irregularity can be continuous or intermittent. In atrial fibrillation, multiple impulses travel through the atria at the same time. Instead of a coordinated contraction, the atrial contractions are irregular, disorganized and very rapid. These irregular impulses reach the AV node in rapid succession, but not all of them make it past the AV node. Therefore, the ventricles beat slower in an irregular rhythm. The resulting rapid, irregular heartbeat causes an irregular pulse and sometimes a sensation of fluttering in the chest.
