Abstract

Pulsed field ablation (PFA) has been in the spotlight as an alternative to conventional thermal energy ablation given its unique tissue selectivity. The concept of current-day PFA is based on traditional direct electric current catheter ablation, creating nanopores in the cell membrane and resulting in cell death. Membrane pores that are created via electroporation can be either permanent, if the electric field is high enough, or only temporary if the fields are sub-threshold. We report a transient block of the accessory pathway after internal electrical cardioversion via a multipolar catheter placed along the tricuspid annulus.

Learning objective

We report a rare case that exhibited a transient accessory pathway conduction block after internal electrical cardioversion via a multipolar catheter placed along the tricuspid annulus. Transient conduction block may be observed by internal electrical cardioversion due to reversible electroporation.

内电性心律转复引起短暂性副通路传导阻滞

脉冲场烧蚀（PFA）由于其独特的组织选择性而成为传统热能烧蚀的替代方法。当前PFA的概念是基于传统的直流电导管消融，在细胞膜上产生纳米孔并导致细胞死亡。如果电场足够高，通过电穿孔产生的膜孔可以是永久性的，如果电场低于阈值，则只能是暂时性的。我们报告了通过沿三尖瓣环放置多极导管进行内部电转复后的短暂副通道阻滞。学习目的我们报告一个罕见的病例，通过沿三尖瓣环放置多极导管进行内部电转复后出现短暂的副通路传导阻滞。可逆性电穿孔引起的内部电复律可观察到瞬态传导阻滞。
