2025年2月22日 · Large multimodal models (LMMs) have enabled new AI-powered applications that help people with visual impairments (PVI) receive natural language descriptions of their surroundings through audible text. We investigated how this emerging paradigm of visual assistance transforms how PVI perform and manage their daily tasks.

The efficacy of pulmonary vein isolation (PVI) as a treatment for drug-refractory atrial fibrillation (AF) has been established through more than 15 years of clinical studies, which have shown consistent, reproducible results worldwide. The PVI technique has evolved to include antral isolation to enhance safety and efficacy.

2025年3月19日 · This study aimed to compare outcomes of pleth variability index (PVi) supported hemodynamic management during early hospital admission with those of standard hemodynamic management. ... competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.

脉搏灌注指数变异(pleth variability index,PVI)是采用一种新型的Masimo Radical-7监测仪通过计算机软件瞬时,连续监测和记录 POP的一种新的计算方法.研究表明,PVI与脉搏氧波幅变异具有很好的相关性(r=0.92,P<(.05),其准确性与有创测得的SVV相类似.目前,有学者将PVI监测应用于 ...

2018年3月15日 · Our meta-analysis, the first of its kind to contrast PVI versus PVI+FIRM ablation, demonstrated no therapeutic benefit of additional focal impulse and rotor modulation approach over PVI alone; long-term arrhythmia-free survival was comparable between the 2 groups, whereas the procedure duration was substantially longer with the addition of ...

脉搏氧灌注指数 (PI)和灌注变异指数 (PVI)是新一代脉搏氧饱和度仪新增的测量参数.PI和PVI分别是连续评价组织灌注和容量状态的无创性监测工具,在危重病救治,麻醉手术和临床研究等方面具有重要价值. 百度学术集成海量学术资源，融合人工智能、深度学习、大数据分析等技术，为科研工作者提供全面快捷的学术服务。 在这里我们保持学习的态度，不忘初心，砥砺前行。

This paper describes the theoretical basis and recent research findings of HPSD or vHPSD ablation and summarizes the state-of-the-art evidence behind the role of this strategy in PVI. Keywords: atrial fibrillation; high-power short-duration; pulmonary vein isolation.
