Introduction:
Treatment of pacemaker circus movement tachycardia (PCMT) in patients with very long VA conduction times may present a problem.
Methods And Results:
PCMT occurred in a 46-year-old woman with an uncommon AV nodal reentrant tachycardia who developed 2:1 AV block after fast pathway radiofrequency catheter (RF) ablation performed at another institution. Due to the long VA conduction time, PCMT could not be prevented by reprogramming the pacemaker or by the addition of antiarrhythmic drugs. Cure of the PCMT was obtained after selective RF ablation of the slow AV nodal pathway.
Conclusion:
RF ablation of the retrograde conduction offers another alternative for treatment of PCMT.
