脈沖電場消融在心律失常中的臨床應用進展
[摘要] 脈沖電場消融是治療心律失常很有前景的新型消融方式,其通過不可逆電穿孔機制增加細胞膜通透性,破壞細胞內(nèi)環(huán)境穩(wěn)態(tài),導致細胞壞死。同時,因它有組織特異性高、非熱性等特點,在心律失常領域中的應用受到追捧。本文對脈沖電場消融的機制、特點及其在心律失常中的臨床應用進展進行綜述。

[Abstract] Pulsed field ablation (PFA) is a promising novel technique for arryhthmia ablation. It increases cell membrane permeability by irreversible electroporation mechanism, destructs intracellular homeostasis, and causes cell death. Meanwhile, due to its characteristics including high tissue specificity and non-thermal ablation, the application of PFA has been more and more attractive in the treatment of arrhythmias. This article reviews the mechanism, characteristics and progress on the clinical application of PFA in arrhythmias.
