Abstract
Since 1969, we applied the radiofrequency pacemaker (named “ATRICON”) to the treatment of various tachycardias. This paper presents the long-term results of this unit in 22 cases of supraventricular tachycardia, 5 WPW syndrome, 2 WPW syndrome+atrial flutter, 1 WPW syndrome+sick sinus syndrome, 3 bradicardia-tachycardia syndrome, 1 ventricular tachycardia. (1) Over a follow-up period of 150 months (mean 89 months), 15 cases could convert tachycardia safely and securely without any problem combined. (2) Four cases have never used Atricon, because of disappearance of tachycardias after operation of combined cardiac diseases. (3) Pacing failure was noted in early 3 cases which was the only complication in this series. (4) Three cases died, but the cause of death had nothing to do with Atricon.
