Filter by:In recent years, radiofrequency ablation has gradually become a first-line treatment for patients with atrial fibrillation. Radiofrequency ablation is an invasive procedure that lasts several hours, patients can experience varying degrees of discomfort and pain despite the use of analgesics. Mindfulness meditation requires the trainer to focus on breathing during the training process, while being non-critical and consciously observing various sensations on the body. It has a good effect in reducing pain, fatigue, negative emotions and strengthening coping with stressful events. With the rapid development of science and technology, meditation is no longer confined to traditional forms. The meditation method with the help of mobile communication technology and brain-computer interface technology can improve efficiency and convenience, and is more personalized. It has been recognized in many studies. The brain-computer interface is to establish a channel between the human brain and the computer that does not rely on conventional brain information output. Using techniques such as electroencephalogram, the spontaneous biopotential of the brain is amplified and recorded from the scalp. This study aims to explore the impact of mindfulness meditation with devices based on brain-computer interface technology on patients undergoing radiofrequency ablation of atrial fibrillation. In order to improve the negative experience of patients during ablation, ensure the safety of patients during ablation, promote postoperative recovery, and increase satisfaction. The pain intensity, fatigue level, anxiety and depression of the meditation group and the control group were compared by the scale. Record relevant vital signs and adverse events. The investigators hypothesized that the pain, fatigue, anxiety and depression of the meditation group would be lower than those of the control group.
Atrial fibrillation (AF) is the most common arrhythmia (irregular heart rhythm), affecting 1-2 million people in the UK. AF significantly increases the risk of an AF-related stroke, heart failure and dementia. A significant proportion of people will have no symptoms, and they may only be found to have AF after suffering an AF-related stroke. An electrocardiogram (ECG) uses sensors placed on the skin to record the heart's electrical activity. A 12-lead ECG uses 10 sensors and is the gold-standard (best available test) to detect any abnormal heart rhythm disturbances. Until recently, a 12-lead ECG showing an irregular heart rhythm was required to make a diagnosis of AF but as AF episodes are often short and unpredictable it may be missed. Therefore, a small device that continuously records heartbeat and heart rhythm could make the diagnosis of arrhythmias and AF much quicker and easier. Accessories such as watches or rings - referred to as wearable devices - have extremely good sensors that measure pulse rate by detecting small changes in skin colour during each heartbeat and can perform a single-lead ECG. Algorithms built in the wearable devices can identify irregular heart rhythms, such as atrial fibrillation. The purpose of this study is to test two new wearable devices - the Skylabs CART-I ring and the Apple Watch - in detecting abnormal heart rhythm recording and recording ECGs. The investigators plan to recruit 500 patients attending Cardiology Departments in several hospitals in the UK and will ask them to wear the Apple Watch and the CART-I and perform 12-lead ECG with each device (two in total). No extra follow-up visits are required. At the end of the study, the investigators will compare interpretation by two cardiologists of the wearable devices' ECGs and the 12-lead ECGs and look at their ability to automatically detect abnormal rhythms.
Cryoballoon ablation has emerged as a safe and effective strategy for treatment of atrial fibrillation (AF) for which it has recently received a 'first-line' therapy indication by the FDA. Pulmonary vein (PV) isolation (PVI) has been the cornerstone of this procedure achieving freedom from recurrent AF in up to ~80% of patients at 12 months of follow-up. However, the success has been shown to be significantly lower, in the range of 50-60% at 3-5 years of follow-up. Other more recent cryoballoon ablation studies have demonstrated marked improvements in clinical outcomes associated with concomitant PVI and cryoballoon ablation/isolation of the 'PV component' (a region of the left atrial posterior [back] wall lying between the PVs that is anatomically and embryologically related to the PVs), versus PVI alone in patients with persistent AF. PVI+PWI using cryoballoon ablation has been widely-practiced in patients with paroxysmal AF. However, the acute/long-term safety and efficacy of this approach has not been formally investigated in paroxysmal AF. Given the mechanistic similarities between persistent and paroxysmal AF, we hypothesize that similar benefits associated with PVI+PWI may also be observed in those with paroxysmal AF. Yet, due to the relative infrequency of breakthrough/recurrent arrhythmias in patients with PAF, to detect a significant difference, large sample sizes and extended follow-up (>24 months) are likely needed. Hence, the aim of this retrospective, observational study is to examine the acute and long-term efficacy and safety beyond 36 months of follow-up associated with PVI alone versus PVI+PWI using cryoballoon ablation in a large cohort of patients with PAF, performed by a single operator (A. Aryana) between 1/1/2014 and 8/31/2018 at Mercy General Hospital.
AFGen1 is indicated for use on symptomatic or asymptomatic adults who are at risk of developing or who have atrial fibrillation, where a software assisted analysis of ambulatory ECG is needed to identify episodes of Afib. The purpose of this study is to establish the clinical performance of the AFib-Chek device (a.k.a. Device) on human participants.
To demonstrate the safety and 12-month effectiveness of the VARIPULSE™ Catheter when used in conjunction with the TRUPULSE™ Generator for pulmonary vein isolation (PVI) in the treatment of subjects with symptomatic paroxysmal atrial fibrillation.
A systematic literature review (SLR) will be conducted to understand the landscape of evidence on the relative safety and effectiveness/efficacy of dronedarone compared to sotalol in patients with AFib within interventional clinical trials and observational studies.
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 Pulsed Field Ablation System Plus-PersAF is a feasible and safe treatment for PersAF and associated AFL
The aim of the study is to demonstrate the performance of Withings WBS08 in the automatic identification of atrial fibrillation and sinus rhythm.
National Institute of Health and Care Excellence (NICE) guidance recommends anticoagulation for stroke prevention in high risk patients with nonvalvular atrial fibrillation (AF). Early evidence suggest that patients with atrial fibrillation (AF) who do not receive anticoagulation are more likely to experience a stroke. However, the characteristics of patients experiencing a first AF-related stroke in real-world settings, who have not been receiving anticoagulation, have not been well documented. It is unclear how the direct anti-FXa oral anticoagulants have been used within real world practice since the introduction of edoxaban in 2015.
Investigators are building an empirical evidence base for real world data through large-scale replication of randomized controlled trials. The investigators' goal is to understand for what types of clinical questions real world data analyses can be conducted with confidence and how to implement such studies.
