Abstract
Since information is still limited whether atrial IK,ACh may become a potential therapeutic target to terminate persistent atrial fibrillation (AF), we assessed it by using the persistent AF canine model with representative IK,ACh inhibitor AVE0118 and class I drugs. AVE0118 (6 mg/kg, n = 7), disopyramide (3 mg/kg, n = 7) and cibenzoline (3 mg/kg, n = 6) terminated the AF in 3/7, 1/7 and 2/6 animals, respectively, whereas aprindine (3 mg/kg, n = 6) did not suppress it. These findings suggest that IK,ACh inhibition in addition to open-state INa suppression with slow dissociation kinetics can synergistically exert potent antiarrhythmic action against persistent AF.
