Abstract Aims We aimed to investigate the safety of discontinuing oral anticoagulation (OAC) therapy after apparently successful atrial fibrillation (AF) ablation, using data from Chinese Atrial Fibrillation Registry study. Methods and results identified 4512 consecutive patients who underwent AF ablation between August 2011 December 2017. Of them, 3149 discontinued OAC 3 months post-ablation (Off-OAC group) 1363 continued beyond this period (On-OAC group). Regular follow-up examinations...
Insertable cardiac monitors (ICMs) are increasingly used for long-term electrocardiographic monitoring. However, the data on ICMs remains limited in China. In this retrospective observational study, we evaluated real-world use and outcomes of patients consecutively receiving Reveal LINQ (Medtronic Ltd, Minneapolis, MN) devices from 2020 to 2022 at Cardiovascular Center Beijing Friendship Hospital. Patient characteristics, ECG parameters, ICM indications follow-up were collected. The...
In this paper, we presented a novel low-cost method for diamond-wire-sawn (DWS) multicrystalline silicon (mc-Si) wafer texturation based on the metal-assisted chemical etching process with Ag/Cu dual elements and nanostructure rebuilding (NSR) treatment to remove saw marks realize uniform invert pyramid textured structures. Benefiting from both increased optical absorption better passivation, an efficiency of 18.71% mc-Si solar cells DWS standard size 156 × mm <sup...
Background The electromechanical dyssynchrony associated with right ventricular pacing (RVP) has been found to have adverse impact on clinical outcomes. Several studies shown that left bundle branch area (LBBAP) superior parameters compared RVP. We aimed assess the difference in synchrony and investigate risk of atrial high-rate episodes (AHREs) patients LBBAP Methods consecutively identified 40 atrioventricular block no prior fibrillation. They were divided according sites: group RVP...
Oxygen-tailoring SiO X /C with highly cycling stability is favorable for forming a covalent interface between and the carbon layer, which further improves its electrochemical performance as promising anode material lithium-ion batteries.
Abstract Background An understanding of the risk factors for atrial fibrillation (AF) progression and associated impacts on clinical prognosis are important future management this common arrhythmia. We aimed to investigate rate from paroxysmal (PAF) more sustained subtypes AF (SAF), progression, its impact adverse outcomes. Methods Results Using data Chinese trial Fibrillation Registry study, we included 8290 PAF patients. Half them underwent initial ablation at enrollment. The main outcomes...
In this paper, Ni was used as an assist metal to fabricate black silicon. nanoparticles were first deposited on the surface of hydrophilic silicon wafer by chemical solution deposition. Then with its etched in a HF/H2O2/H2O mixed at room temperature. The concentration HF changed study reaction principle assisted etching. A reflectivity low 2.31% wavelength range 400–900 nm obtained optimized condition. An 'inverted pyramid + nano-pore' structure could be formed when etching time long enough...
An increase in the incidence of atrial fibrillation (AF) during acute phase myocardial infarction (AMI) has been observed. But it is still unclear whether implications new-onset AF on in-hospital and long-term prognosis are similar magnitude.Using data from CBD Bank study, 3,824 consecutive AMI patients, without prior AF, were analyzed. During index hospitalization, all patients monitored by continuous cardiac monitoring, twice daily performed 12- or 18-lead ECGs timely ECG checks when...
Various gas sensors have made considerable improvements to the quality of people's lives. However, in most cases, changing materials is necessary adapt target gas, which limits further application sensors. To meet this challenge, work, molecular imprinting (MI) technology introduced. Acrylic acid used as a functional monomer, while molecules, including acetone, are templates. The MI process with an acetone template helps improve selectivity TiO2 by up 1.74-2.80 times. Moreover, it proved...
Metal‐assisted chemical etching (MACE) method is an efficient way to improve the power conversion efficiency of solar cell by developing nanostructures. Normally, hydrogen peroxide widely used as oxidizing agent, through which anisotropic nanostructures could be achieved. Here, nanoscale textured multi‐crystalline silicon (mc‐Si) with 18.13% was fabricated MACE potassium permanganate (KMnO 4 ) agent. The isotropic KMnO showed great uniformity surface reflectance, corresponding oval pits....
The absence of an effective texturing technique for diamond-wire sawn multi-crystalline silicon (DWS mc-Si) solar cells has hindered commercial upgrading from traditional multi-wire slurry (MWSS cells. In this work, we present a novel method the removal diamond-wire-sawn marks in wafer based on metal assisted chemical etching process with Cu/Ag dual elements and nano-structure rebuilding (NSR) treatment to make uniform inverted pyramid textured structure. temperature effect NSR solution was...
Acid texture is difficult for diamond wire sawn (DWS) multicrystalline silicon (mc‐Si) wafer owing to the inhomogeneous distribution of damage layer on surface. In this article, metal‐assisted chemical etching (MACE) has been selected introducing a porous seeding induce acid texturing etching. SEM results show that oval pit structures coverage get obvious improvement even smooth areas. Owing further improved light absorption ability by second MACE and nanostructure rebuilding (NSR) process,...
H 2 O is predominantly used as an oxidizer in traditional metal assisted chemical etching (MACE), showing a high consumption rate due to its instability at room temperature. In this work, low concentration HNO 3 instead of investigated Ag‐assisted process for multicrystalline silicon (mc‐Si) wafer. comparative experiments, black wafers with surface reflection 6.46% are obtained using only 5% molar quantity . After post nanostructure rebuilding treatment, nano‐scale inverted pyramid‐like...
