Filter by:The study is a phd-study comprising several substudies focusing on cardiac arrhythmias, mainly atrial fibrillation, among Greenlanders in Greenland. Some previous studies have indicated that the prevalence may be lower than among Westerners, however; studies have also indicated that atrial fibrillation is underdiagnosed. These studies aim to: - Estimate the prevalence of AF among Greenlanders in Greenland aged 55 years or older. - Estimate the prevalence of well-known risk factors among those found to have AF - Explore the symptoms of those affected by AF in Greenland - Among part of the participants: estimate the prevalence of autonomic neuropathy as this may cause arrhythmias.
The study investigates the performance pf PulseOn Arrhythmia Monitor System that includes a wrist-worn device, which combines continuous optical heartbeat interval monitoring and intermittent ECG measurement, and a data management system used by healthcare professionals for data observation, in the detection of previously undiagnosed cardiac arrhythmias, especially atrial fibrillation.
This study will develop a whole-of-body markerless tracking method for measuring the motion of the tumour and surrounding organs during radiation therapy to enable real-time image guidance. Routinely acquired patient data will be used to improve the training, testing and accuracy of a whole-of-body markerless tracking method. When the markerless tracking method is sufficiently advanced, according to the PI of each of the data collection sites, the markerless tracking method will be run in parallel to, but not intervening with, patient treatments during data acquisition.
A multi-center clinical trial to explore the status of collection and transmission of electrocardiogram using a wearable device
The objective of this observational study is to assess clinical benefits of innovative features (e.g. Bluetooth technology and smartphone patient applications) in a patient population that is implanted with standard indication for implantable cardiac defibrillator.
The current study concerns Cardiags Trimod, a new non-invasive medical device for cardiac examinations. The evaluation of its effectiveness is done relative to specific standard devices.
Precise identification of the atrial fibrosis is essential for successful catheter ablation of atrial arrhythmias in patients with atrial fibrillation. Voltage mapping of endocardial electrograms is currently used to delineate the anatomical substrate, but this is influenced by the direction of the activation wave front and is limited by the patient-specific thresholds. Mapping of local myocardial electrical impedance may overcome these limitations.
The objective of this project is to evaluate the capability of a specific mobile electrocardiogram monitoring of detecting arrhythmic events in children with history of palpitation and or syncope. We will compare this approach with the standard approach of clinical follow-up plus 24-hour Holter ECG monitoring in terms of acceptability and ability to identify significant arrhythmias.
The primary objective is to evaluate the safety and technical performance of the CathVision Cube® System. The secondary objective is to benchmark the intracardiac electrogram signal quality compared to commercially available systems in patients undergoing assessment and ablation of cardiac arrhythmias.
