Ventricular ectopy following accessory pathway ablation in WPW syndrome star

ABSTR A C T Introduction: Many Authors already described automatic activity arising from accessory pathways, but the under-lying mechanism has not been clarified yet. They may be due to embryogenetic features of myocardium or may be related to specific excitability during radiofrequency ablation. Case: Our report shows that ventricular accelerated rhythm may transiently arise from the ventricular edge of a common myocardium made accessory pathway right after the ablation. No further action were required in our experience, since the phenomenon self extinguished in approximately hour. Conclusions: If this manifestation represents the effect of thermal injury or if it is a real intrinsic automaticity is not fully documented and may need further reporting and investigation.
