Introduction

Many Authors already described automatic activity arising from accessory pathways, but the underlying 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.

WPW综合征旁路消融术后室性异位

介绍

许多作者已经描述了由旁路引起的自动活动，但潜在机制尚未阐明。它们可能是由于心肌的胚胎遗传特征或可能与射频消融期间的特定兴奋性有关。

案件

我们的报告显示，心室加速节律可能在消融后立即由旁路心肌的共同心肌的心室边缘产生。根据我们的经验，不需要采取进一步行动，因为该现象在大约 1 小时内自行消失。

结论

如果这种表现代表热损伤的影响，或者它是否是真正的内在自动性，则没有完全记录下来，可能需要进一步报告和调查。
