NCT ID: NCT05367141 Completed - Atrial Fibrillation Clinical Trials

Improvement Adherence to Clinical Practice Guidelines Using the Clinical Decision Support System in Patients With Hypertension and Atrial Fibrillation

INTELLECTII
Start date: May 17, 2022
Phase: N/A
Study type: Interventional

The Clinical Decision Support Systems (CDSS) based on real clinical data and its own algorithms can help to make the right choice according to guidelines. The goal of the INTELLECT II study is to investigate treatment adherence to guidelines/science-based medicine and its impact on patient outcomes into two groups of doctors, clinical centers with standard care of treatment (control), and clinical centers using CDSS (active).

NCT ID: NCT05366803 Completed - Atrial Fibrillation Clinical Trials

Women's Health Initiative Silent Atrial Fibrillation Recording Study

WHISH STAR
Start date: September 8, 2017
Phase: N/A
Study type: Interventional

The purpose of the WHISH STAR study is to investigate whether or not those who are randomized to exercise intervention have higher rates of atrial fibrillation on review of medical records and, in a subset, on screening with a cardiac ECG patch monitor. We will also study whether those with a known history of AF have any changes in AF hospitalizations due to exercise.

Interventional, prospective, non-randomized, single-center, non-controlled clinical investigation as part of the premarket clinical evaluation of VX1+ medical device, aiming to verify that VX1+ in bidirectional configuration with auto-tagging function is both ergonomic and reliable for dispersed electrograms detection and automatic tagging on 3D-map in real-time.

NCT ID: NCT05357716 Completed - Atrial Fibrillation Clinical Trials

Preliminary Research Evaluation for Ambulatory Leadless Electrocardiogram Recorder Trial

PRE-ALERT
Start date: November 15, 2020
Phase:
Study type: Observational

The clinical study is intended to implement and test the collection and analysis of paired ECG data from the HeartWatch and two comparator devices, an Event Recorder and Holter. The HeartWatch is indicated for extended diagnostic evaluation of patients with transient symptoms of possible cardiac origin such as syncope and palpitations, as well as patients at risk for arrhythmias, but without significant symptoms. While the use of the device itself can be managed by both healthcare professionals and patients, interpretation of the collected data for diagnosis is restricted to healthcare professionals, as the data must be loaded and analyzed separately after recording. Patients indicated for extended ambulatory ECG testing will be approached for participation. Subjects will wear the HeartWatch and an Event Recorder for up to 72 hours or the HeartWatch and Holter monitor for up to 48 hours. Subjects will be asked to document their activities (standing, sitting, walking, exercise, or laying down). Event recorder subjects will collect user-triggered and auto-triggered data, while Holter subjects will record diary information on their activities and any relevant symptoms. Adverse events and user preference for one device versus the other being used in that arm will also be collected from all subjects. Paired ECG data from the HeartWatch and comparator devices is expected to be similar in terms of the events documented and the proportion of data that is clinically interpretable.

NCT ID: NCT05350397 Completed - Atrial Fibrillation Clinical Trials

How Important Is Acupressure Application in Balancing Heart Rate and Blood Pressure in the Treatment of Atrial Fibrillation? Single-Blind Randomized Experimental Study

Start date: February 20, 2018
Phase: N/A
Study type: Interventional

Atrial fibrillation is a common cardiac arrhythmia affecting 1-2% of the population. This rate is expected to increase in the next 30 years. The aim of this study is to determine the effect of acupressure applied to patients with chronic atrial fibrillation on blood pressure and heart rate. This study was designed as a randomized, placebo-controlled experimental study. As a result of the power analysis, 3 groups were formed, each consisting of 23 subjects. No procedure was applied to the control group before and after the measurements. In patients in the placebo group, an inverted and loose acupressure wristband was attached to the Shenman point to avoid applying pressure to any part of the wrist. Acupressure wristbands were applied towards the Shenmen point to provide adequate pressure to the patients in the intervention group and acupressure was applied twice a day. Acupressure was applied 4 times in two days.

NCT ID: NCT05343923 Completed - Atrial Fibrillation Clinical Trials

Atrial Fibrillation Characterization on Paroxysmal and Persistent Patients

PAPER-AF
Start date: June 1, 2021
Phase:
Study type: Observational

Background and Hypothesis: Atrial Fibrillation (AF) treatment strategies have limitations. The efficacy of the procedure depends in several factors such as age, AF duration, atrial diameter and atrial electrophysiological behavior, determining what has been termed as atrial substrate. Therefore, the effectiveness of one specific treatment such as the ablation procedure, will be determined by the areas responsible for the maintenance of the fibrillation and its modification and/or elimination. The identification of these areas with a clear description of the arrhythmic substrate is one of the most important factors to determine new biomarkers that explain, at electrophysiological level, the properties of the substrate and therefore, increase the acute efficacy and long-term effectiveness of the treatment.

NCT ID: NCT05321810 Completed - Clinical trials for Non-valvular Atrial Fibrillation

NCT ID: NCT05319769 Completed - Atrial Fibrillation Clinical Trials

Non Fluoroscopic APpROach iN atriaL Fibrillation Ablation procEdureS

APRONLESS
Start date: June 1, 2020
Phase:
Study type: Observational

In electrophysiology, interventional procedures are often assisted by fluoroscopic guidance, exposing both patients and healthcare professionals to a considerable dose of radiation. Catheter ablation of atrial fibrillation has frequently involved the use of fluoroscopy: in fact, it incorporates greater complexity due to the need to perform the transseptal puncture. A visible introducer in the 3D electro-anatomical mapping system (which does not involve the use of X-rays), has become an important tool for performing transseptal puncture: in particular, it is positioned at level of the oval fossa of the right atrium (puncture site); subsequently, the needle is introduced inside it; the intervention is guided both by electroanatomical mapping and by the use of intracardiac echocardiography for the identification of important anatomical landmarks. The "zero rays" technique represents a valid alternative to fluoroscopic guidance, widely used and validated over the years. In fact, X-ray exposure in an atrial fibrillation ablation procedure can reach up to 60 mSv: the radiological risk makes it necessary to study safe and effective alternative techniques. In this retrospective, observational and monocentric study, 50 catheter ablation procedures of atrial fibrillation will be examined, divided into two groups: 1. 25 patients who performed this procedure according to the classic approach, ie under fluoroscopic guidance; 2. 25 patients who performed this procedure using an ablative approach that involved the use of the introducer in combination with the 3D EAM system and intracardiac echocardiography. Clinical efficacy will be assessed through a cardiological checkup and 24-hour electrocardiographic recording (ECG Holter) at 6 months.
