中华医学杂志(英文版) 2024年第14期137卷 1747-1749页

To the Editor: Pulmonary vein antral isolation (PVAI) is the cornerstone of catheter ablation techniques used in the treatment of patients with atrial fibrillation (AF). However, the outcomes of a PVAI-only strategy for persistent AF have proven suboptimal. The majority of patients with persistent AF may require further atrial ablation beyond PVAI. Ablation of AF drivers, a patient-tailored ablation strategy for persistent AF with a procedural endpoint of AF termination, has garnered increasing attention in recent years. We aimed to determine the electrogram (EGM) characteristics of AF drivers that can predict AF termination.

利用电化学测试、SEM、EDS、XPS等方法研究了AlCoCrFeNi_(2.1)共晶高熵合金(EHEA)在0.05 mol/L H_(2)SO_(4)溶液与0.05 mol/L H_(2)SO_(4)+0.02 mol/L NaCl溶液中的腐蚀行为。结果表明,AlCoCrFeNi_(2.1)EHEA在H_(2)SO_(4)溶液中的钝化行为与局部腐蚀受Cl-影响明显;Cl-不改变AlCoCrFeNi_(2.1)EHEA钝化膜的半导体类型,但对钝化膜的致密性影响明显;钝化膜中的Ni受Cl-影响较小,Cl-主要通过影响Al、Cr氧化物的含量进而改变钝化膜的性质;在0.05 mol/L H_(2)SO_(4)溶液中,AlCoCrFeNi_(2.1)EHEA的腐蚀为富Ni-Al相选择性溶解;在0.05 mol/L H_(2)SO_(4)+0.02 mol/L NaCl溶液中,则为点蚀与选择性溶解。
