The Effect of KCl on Atrial Fibrillation Caused by Acetylcholine
Atrial fibrillation can be produced in the heart-lung preparation of the dog by the slow infusion of acetylcholine and the application of electric stimuli to the auricle. The fibrillation can then be maintained indefinitely, after stimulation ceases, by continuing the infusion of acetylcholine. The fibrillation can be restored to normal rhythm by the infusion of KCl. This throws light on the action of acetylcholine in maintaining atrial fibrillation.
