Trigger activity of ryanodine in mechanism of cholinergic atrial fibrillation in dogs

摘要: Systemic infusion of ryanodine did not prevent induction atrial fibrillation (AF) during acetylcholine (Ach) perfusion in frogs. The AF, however, appeared later as the dogs/Ach start and lasted for a shorter time compared with control. activation mapping right atrium showed no significant difference from findings suggest that mechanism AF is hardly related to triggering activity, at least this particular model.
