[Noninvasive cardioversion of atrial tachycardia using dual-chamber definitive stimulator].
Many authors report clinical cases of successful interruption of tachyarrhythmias using special pulse generators endowed with an antitachycardia program. Nevertheless, in some cases, it is possible to obtain the same outcome using multiprogrammable pacemakers without this program. We describe one of these cases in a very old patient with brady-tachyarrhythmia syndrome. During atrial tachycardia (120 bpm) pacer was set in AAI at the highest programmable rate (130 bpm) obtaining an overdrive atrial pacing which was able to stop the arrhythmia, restoring rhythm by pulse generator. In conclusion, overdrive of atrial tachycardia using an implanted pacemaker, seems to be a correct clinical approach.
