Catheter ablation has become a cornerstone in atrial fibrillation (AF) therapy, improving freedom from all-atrial arrhythmias, as well as outperforming antiarrhythmic drugs in alleviating AF-related symptoms, reducing hospitalizations, and enhancing quality of life. Nevertheless, the success rate of traditional radiofrequency ablation (RFA) methods remains less than ideal. To address these issues, refinement in RFA strategies has been developed to improve efficacy and laboratory efficiency during pulmonary vein isolation (PVI). High-power short-duration (HPSD) RFA has emerged as a safe strategy to reduce the time required to produce durable lesions. This article reviews critical aspects of HPSD ablation in the management of both paroxysmal and persistent AF, covering aspects such as effectiveness, safety, procedural intricacies, and the underlying biophysics.
导管消融已成为心房颤动（AF）治疗的基石，提高了无房性心律失常的发生率，并且在缓解房颤相关症状、减少住院次数和提高生活质量方面优于抗心律失常药物。然而，传统射频消融（RFA）方法的成功率仍不尽人意。为了解决这些问题，人们对RFA策略进行了改进，以提高肺静脉隔离（PVI）期间的疗效和实验室效率。高功率短持续时间（HPSD）RFA已成为一种安全的策略，可减少产生持久损伤所需的时间。本文综述了HPSD消融在阵发性和持续性房颤管理中的关键方面，包括有效性、安全性、操作复杂性和潜在的生物物理学等方面。
