Filter by:The WatchQT study will compare the performance of a smartwatch combined with Cardiologs ECG AI Analysis system in monitoring corrected QT (QTc) intervals with that measured on a manually read 12-lead ECG in subjects with Normal Sinus Rhythm (NSR) during antiarrhythmic drug (AAD) initiation and follow-up at the hospital.
The objective of this safety and feasibility study is to assess whether the endocardial creation of electrically nonconductive lesions via PEF catheter ablation applied using the FARAPULSE Cardiac Ablation System Plus is a feasible and safe treatment for PersAF and associated AFL
Direct current cardioversion (DCCV) is a widespread method to restore sinus rhythm in patients with atrial fibrillation. It is a safe and effective method of treating atrial fibrillation. In this study, the investigators want to compare two algorithms. The rational one, with lower initial energy and the second one with the maximum possible shock energy.
This study examined patients on taking oral anticoagulants (OACs) are often prescribed for Atrial fibrillation (AFib) to determine the effectiveness of a multiple interactive health education program, which was developed based on the health belief model (HBM) and incorporated information technologies.
Atrial Fibrillation (AF) is a common heart rhythm condition that affects over 3% of the total population. AF can lead to serious health problems such as heart failure or stroke and can also cause troublesome symptoms in some people. Although many advances have been made, there remains a pressing need to improvement treatment of AF. It is increasingly recognised that the brain and nerves can influence the electrical activity of the heart. Therefore, this research involves studying a new nerve target (Subclavian ansae) that is connected to the heart and can be a potential target for future treatment of AF. This nerve lies around an area close to an artery that runs to participant's left arm called left subclavian artery which can be approached via leg (key hole). The investigators aim to conduct this study in patients who have been referred for first time AF ablation.
Anticoagulation monitoring is done by monitoring the ACT (Activated Clotting Time) with an objective greater than 300 s. Until now, treatment with direct oral anticoagulant (for the prevention of thromboembolic events of atrial fibrillation) was interrupted a few days before the procedure in order to limit the risk of per-procedural bleeding. However, 3 recent randomized studies concerning the 3 DOACs available suggest that treatment should not be interrupted during the entire operative period. The operation therefore takes place under double anticoagulation with a direct oral anticoagulant and unfractionated heparin. Under these conditions, ACT monitoring can no longer be considered a reliable means of measuring the level of anticoagulation. It was therefore necessary to explore the hemostasis of these patients in a broad way in order to avoid any risk of overdose of UFH (Unfractionated Heparin) during the procedure.
This is a randomized controlled trial (RCT) to test a novel artificial intelligence (AI)-enabled electrocardiogram (ECG)-based screening tool for improving the diagnosis and management of Atrial Fibrillation.
This is a prospective, multicenter, randomized clinical evaluation of the Sphere-9 Mapping and Ablation Catheter with the Affera Mapping and Ablation System. Subjects will be randomly assigned 1:1 to receive treatment with either the Sphere-9 Mapping and Ablation Catheter and the Affera Mapping and Ablation System (investigational device) or the THERMOCOOL SMARTTOUCH® SF radiofrequency ablation catheter (control device).
The purpose of this clinical trial is to evaluate the safety and efficacy of a pulsed field ablation system developed and manufactured by Hangzhou Dinova EP Technology Co., Ltd in the treatment of patients with paroxysmal atrial fibrillation
Evaluation of the predictive value of serum levels of adipocytokines and primary phase reactant for recurrent atrial fibrillation (RAF) after catheter ablation in 26 patients had persistent and 91 patients had paroxysmal AF. During 12-m follow-up, 41 patients had RAF (35%). Patients had RAF were significantly older, had significantly higher BMI, lower ejection fraction and wider maximal left atrial diameter (LAD). Serum hs-CRP, IL-6, TNF-α, visfatin, and adiponectin levels were significantly higher in patients developed. Elevated serum levels of TNF-α, visfatin and adiponectin are a significant positive predictors for RAF.
