Termination of ventricular tachycardia with bursts of rapid ventricular pacing

摘要: Bursts of rapid ventricular pacing used during 573 episodes tachycardia in 23 patients terminated 5 12 (89 percent), with burst rates averaging 56 beats/min above the rate, for to 10 captures. Tachycardia was accelerated by bursts below 300 16 (3 percent); these spontaneously or responded further bursts. Acceleration heart rate more than fibrillation occurred six times (1 each episode requiring direct current cardioversion. Pacing had no effect 38 instances (7 mostly terminal cardiogenic shock. Implantable pacemakers delivering were placed two who have units at home. No deaths associated pacing, which is an effective, rapid, pleasant alternative repeated cardioversion and a useful tool electrophysiologic testing recurrent tachycardia.
