View clinical trials related to Atrial Fibrillation Paroxysmal.
Filter by:Atrial fibrillation is a cardiac arrhythmia commonly encountered in a primary care setting. Current screening is limited to pulse palpation and ECG confirmation when an irregular pulse is found. Paroxysmal atrial fibrillation will, however, still be difficult to pick up. With the advent of smartphones, screening could be more cost-efficient by making use of simple applications, lowering the need for intensive screening to discover (paroxysmal) atrial fibrillation. This cluster randomized trial will examine the effect of using a smartphone-based application such as FibriCheck® on the detection rate of atrial fibrillation in a Flemish general practice population. This study will be conducted in 22 primary care practices across the Flanders region of Belgium and will last 12 months. Patients above 65 years of age will be divided in control and intervention groups on the practice level. The control group will be subjected to standard opportunistic screening only, while the intervention group will be prescribed the FibriCheck® app on top of this opportunistic screening. The difference in detection rate between control and intervention groups will be calculated at the end of the study. The investigators will use the online platform INTEGO for pseudonymized data collection and analysis, and risk calculation. Smartphone applications might offer a way to cost-effectively screen for (paroxysmal) atrial fibrillation in a primary care setting. This could open the door for the update of future screening guidelines.
The purpose of this study is to collect data on laser ballon (2nd gen) systems for catheter ablation for AF, in order to determine the safety and the efficacy of this technique. Moreover, the investigators aim to determine the short and long term outcomes of pulmonary vein isolation evaluating arrhythmia recurrence, especially using continuous rhythm monitoring with implantable loop recorders (ILR).
Atrial fibrillation (AF) is one of the most common forms of heart rhythm disorder in patients with cardiovascular diseases. The choice of treatment for AF is a complex problem, depending on the form (paroxysmal, persistent, permanent) of AF, clinical manifestations of cardiac arrhythmias, associated diseases, the effectiveness of antiarrhythmic drugs. The accumulated data to date indicate an efficacy of the method of radiofrequency ablation (RFA) in the treatment of the paroxysmal form of AF. The RFA procedure does not eliminate the pathological processes that take place during developed AF. This dictates the need to develop and test new technologies and physical rehabilitation programmes for patients. The positive clinical effects of physical rehabilitation programmes based on moderate-intensity exercises are well known. The search for drugs capable of improving the results of RFA for AF in patients becomes urgent. This creates the prerequisites for the study of the clinical efficacy of trimetazidine MV in the rehabilitation of patients with cardiac diseases who underwent treatment of AF with RFA, which will optimize the management of such patients in the inpatient and outpatient setting.
Pulmonary vein isolation (PVI) is the cornerstone of catheter ablation procedures in patients with paroxysmal atrial fibrillation (PAF) [1]. However, the incidence of atrial fibrillation (AF) recurrence remains high [2], mostly due to pulmonary vein (PV) reconnection [1], emphasizing the formation of transmural lesions to achieve complete conduction block along the ablation lines [3]. Previous studies have shown that elimination of the negative component of the unipolar electrogram (UP-EGM) during radiofrequency applications reflects transmural lesions. The persistence of such a negative component consistently corresponds to non-trans mural lesions [4].
Rationale: Although there are several individual factors which are known to influence the chances of successful atrial fibrillation (AF) ablation, it remains a challenge to identify patients at risk for ablation failure with satisfactory certainty. Objectives: To identify predictors of success of AF ablation including clinical factors, AF recurrence patterns, anatomical and electrophysiological characteristics, circulating biomarkers and individual genetic background. Study design: Prospective registry of patients undergoing AF ablation. Clinical characteristics and results of routine tests are collected. In addition, the following (non-standard) tests are performed: extended surface electrocardiogram (extECG), extended rhythm monitoring, biomarker testing, genetic analysis, questionnaires. In subgroups of patients transesophageal electrocardiogram (TE-ECG), epicardial electroanatomical mapping and/or left atrial appendage (LAA) biopsy is performed. Study population: Patients aged 18 years and older with documented AF, scheduled for AF ablation. Main study endpoints: Ablation success after 12 and 24 months, defined as freedom from any episode of documented atrial arrhythmia after the blanking period.
A randomized patient-oriented trial to investigate whether continual symptomatic use of the Kardia Mobile monitoring device is a superior strategy for diagnosing Atrial Fibrillation (AF) in comparison to normal ambulatory monitoring with a 24-hour Holter monitor. Patients with referrals to an Electrophysiologist, symptoms of AF but no documentation of AF, and with at least one stroke risk factor based on the CHADS2 scoring system are randomized 1:1 to Kardia Mobile monitoring versus Holter monitoring alone.
Assess the clinical safety and feasibility of MultiPulse Therapy (MPT) electrical stimulation waveform sequence in terminating paroxysmal and persistent atrial fibrillation.
This study is a prospective, randomized controlled study to compare overall clinical outcomes between High Power Short Duration (HPSD) and standard radiofrequency (RF) ablation settings for Atrial Fibrillation (AF) ablation in the treatment of subjects with paroxysmal or persistent Atrial Fibrillation.
It is a prospective, randomized and double-blind clinical trial involving an invasive technique for isolation of pulmonary veins (PVAC gold) in relation to clinical treatment during an one year of segment. The patients included have paroxysmal atrial fibrillation (aged 65 years and older) refractory to antiarrhythmic treatments that do not have structural and / or ischemic heart diseases. This trial employed quality of life scores prior to the study and during the sixth and twelfth month of the segment, electrocardiograms and holter of 24 hours. The proposed imaging tests was the transesophageal echocardiogram before each procedure. The cerebral MRI was performed in the 24 hours post invasive procedure and Angio-tomography of the pulmonary veins in the 6-month segment.
The objectives of the investigators are to demonstrate a reduction in frequency and symptoms of AF and improvements in cardiovascular risk factors following a lifestyle intervention in patients with paroxysmal AF. Participants will be randomized into control or intervention groups. The intervention will receive step trackers, diet counselling, an exercise program, and risk factor modification consultations. Controls will receive step trackers and care as usual. Testing will occur at baseline, six months, and one year.
