Episodes of paroxysmal atrial fibrillation (PAF) in the ambulatory patient might be terminated promptly by intravenous infusion from an implanted drug delivery system. We have explored this concept in a series of experiments using rapid intra-atrial infusions in dogs. In the acute studies, rapid intra-atrial infusions of procainamide were delivered during continual measurements of epicardial monophasic action potentials (MAP), atrial effective refractory periods (ERP), and right to left atrial conduction times (CT) in 9 dogs. In the chronic studies, 20 episodes of sustained PAF were induced in 4 dogs after six weeks of rapid or burst atrial pacing from a specially programmed implanted pacemaker. Rapid infusions of procainamide were then delivered to the right atrium through a previously implanted catheter connected to a subcutaneous access port. Procainamide significantly increased the duration of the atrial MAP, ERP and CT in the acute experiments. It also terminated induced PAF within five minutes of the end of infusion in all twenty of the chronic experiments. We conclude that rapid intra-atrial infusion of procainamide is very effective in this animal model of PAF, and that such infusion prolongs atrial MAP, ERP and CT.
