Filter by:The primary objectives for the registry is to evaluate the overall incidence of serious complications or adverse events for primary implants and replacement devices, and assess the cost and time efficiency for both physicians and patients. The Registry is a multi ASC data collection registry. Data collection will occur at the time of screening, implant, and 2 weeks after implant at the time of wound check.
This is an open-label study to investigate the functional features of prolonged monitoring by 14-day EZYPRO® to improve the medical care and/or diagnosis for the patient with arrhythmia. Patients will be enrolled by outpatient basis from two clinical study sites. Enrolled patients will wear a traditional 24-hour Holter monitor and an 14-day EZYPRO® which can provide monitoring data for up to 14 days. This study will allow a direct comparison between two devices.
Hypoglycemia, frequently asymptomatic, may lead to cardiac arrythmias and induce an increased risk of cardiovascular morbidity and mortality in patients with type 2 diabetes (T2D). The study hypothesize is that the hypoglycemia reduction, achieved with the FREESTYLE LIBRE device, a Glucose Continuous Monitoring system, may decrease cardiac arrythmias associated with hypoglycemia. So the main objective is to evaluate the efficacy of the FREESTYLE LIBRE system, associated with a specific therapeutic education on the cardiac arrythmias reduction, compared to a capillary ASG system with standard therapeutic education, in patient with T2D with high risk of hypoglycemia. This is a open, multicenter, controlled, randomized study in parallel group.
This is a purely observational project and the objectives are to record and analyze the local potentials at the site of Premature Ventricular Contraction (VPC) focus through the Rhythmia system, ti determine the short and long-term success of the procedure and compare it to the existing literature about standard procedures, to highlight the advantages of the system compared to conventional mapping and to characterize optimal pace map or activation map as achieved by the Rhythmia system.
A Retrospective Propensity Matched Study comparing: - real zero fluoroscopy catheter ablation - conventional fluoroscopy catheter ablation without 3D system - conventional fluoroscopy catheter ablation with 3D system
This is a Canadian multicenter randomized controlled trial to assess remote patient management. Patients will be randomized to remote patient management versus usual care, and will be stratified by RemoteView vs no RemoteView utilization, as well as by center.
Participants in the Snap arm were instructed to undertake once-day recording and transmission of a 30-second single-lead iECG trace to a secure server, plus additional submissions if symptomatic over a 3-month period. Snap traces were analyzed by an automated analysis software and cardiologists. Clinical review and appropriate care was arranged for those clinically significant arrhythmia. Patients in the RC group were followed up as normal methods including ECG, Holter.
The objective of the RHAPSODY study is to evaluate the performance of new software features in subjects undergoing standard of care catheter-based endocardial mapping for atrial or ventricular tachyarrhythmias using a commercial Rhythmia Mapping System. Results from this study will be used to guide development and refinement of new software features that may be implemented in future commercial software releases.
Arrhythmogenic ventricular cardiomyopathy (AVC) is a genetic condition which affects the heart and can lead to heart failure and rhythm problems, of which, sudden cardiac arrest or death is the most tragic and dangerous. Diagnosis and screening of blood-relatives is very difficult as the disease process can be subtle, but sufficient enough, so that the first event is sudden death. The Mayo Clinic AVC Registry is a collaboration between Mayo Clinic, Rochester, USA and Papworth Hospital, Cambridge University Hospitals, Cambridge, UK. The investigators aim to enroll patients with a history of AVC or sudden cardiac death which may be due to AVC, from the US and UK. Family members who are blood-relatives will also be invited, including those who do not have the condition. Data collected include symptoms, ECG, echocardiographic, MRI, Holter, loop recorder, biopsies, exercise stress testing, blood, buccal and saliva samples. Objectives of the study: 1. Discover new genes or altered genes (variants) which cause AVC 2. Identify biomarkers which predict (2a) disease onset, (2b) disease progression, (2c) and the likelihood of arrhythmia (ventricular, supra-ventricular and atrial fibrillation) 3. Correlate genotype with phenotype in confirmed cases of AVC followed longitudinally using clinical, electrocardiographic and imaging data. 4. Characterize desmosomal changes in buccal mucosal cells with genotype and validate with gold-standard endomyocardial biopsies
Fetal research and clinical practice has been hampered by a lack of suitable investigational techniques. Currently, ultrasound is the only widely used method of studying fetal anatomy and physiology, but it has significant limitations for assessment of cardiac rhythm. The proposed study will allow the investigators to evaluate fetal magnetocardiography (fMCG) as a new tool for the study of normal and abnormal fetal heart rate and rhythm.
