Abstract

Cardiac arrhythmias occur at all ages. Cardiac mapping and ablation are established methods for curing arrhythmia substrates; however, complications may occur. We report a patient with transient Wenckebach heart block during radiofrequency ablation in the setting of Wolff Parkinson White syndrome despite the ablation catheter being well away from the atrioventricular node, and we speculate on the potential mechanism.
