Radiofrequency Catheter Ablation of Parahisian Accessory Pathway
Journal of Interdisciplinary Medicine, 2016 Radiofrequency catheter ablation of parahisian accessory pathways in pre-excitation syndrome is a challenging task, due to the extremely high risk of complete atrioventricular block.

Clinical characteristics of patients with atrial flutter before radiofrequency ablation
Journal of V. N. Karazin Kharkiv National University: Series Medicine, 2020 Introduction. Radiofrequency ablation (RFA) is today the method of choice for the ineffective medical treatment of atrial fibrillation (AF), but its course is often complicated by comorbid pathology.

Laser ablation loading of a radiofrequency ion trap [PDF]
Applied Physics B 107, 883 (2012), 2011 The production of ions via laser ablation for the loading of radiofrequency (RF) ion traps is investigated using a nitrogen laser with a maximum pulse energy of 0.17 mJ and a peak intensity of about 250 MW/cm^2. A time-of-flight mass spectrometer is used to measure the ion yield and the distribution of the charge states. Singly charged ions of elements

From Basics to Frontiers: A Comprehensive Review of Plasma-Modified and Plasma-Synthesized Polymer Films [PDF]
Polymers (2023), 2023 This comprehensive review begins by tracing the historical development and progress of cold plasma technology as an innovative approach to polymer engineering. The study emphasizes the versatility of cold plasma derived from a variety of sources including low-pressure glow discharges (e.g., radiofrequency capacitively coupled plasmas) and atmospheric ...

Laser ablation production of Ba, Ca, Dy, Er, La, Lu, and Yb ions [PDF]
Appl. Phys. B 123, 99 (2017), 2016 We use a pulsed nitrogen laser to produce atomic ions by laser ablation, measuring the relative ion yield for several elements, including some that have only recently been proposed for use in cold trapped ion experiments. For barium, we monitor the ion yield as a function of the number of applied ablation pulses for different substrates.

Effect of energy dissipation on radiofrequency ablation model in cardiac tissue: modelling, analysis and numerical simulation [PDF]
arXiv, 2023 This paper deals with the mathematical analysis and numerical simulation of a new nonlinear ablation system modeling radiofrequency ablation phenomena in cardiac tissue, {which incorporates the effects of blood flow on the heat generated when ablation by radiofrequency. The model also considers the effects of viscous energy dissipation.

Radiofrequency ablation in pancreatic cancer [PDF]
HPB, 2006 Radiofrequency ablation (RFA) is effective in the treatment of unresectable hepatic tumors and promising results have also been described in tumors of kidney, lung, brain, prostate, and breast. The radiofrequency destruction of solid pancreatic tumors sounds logical but also seems risky due to the friable pancreatic parenchyma, the fear of pancreatitis
