Filter by:The purpose of this study is to determine whether Enhanced device programming to reduce therapies (i.e. anti tachycardia pacing (ATP) episodes and shocks (both appropriate and inappropriate)) is safe for patients implanted with an Implantable Cardioverter-Defibrillator (ICD). The secondary objective is to examine the impact of Enhanced programming on (i) ATPs and shocks (both appropriate and inappropriate) and (ii) quality of life and distress.
The main objective of the European Pediatric Catheter Ablation Registry is to collect data on ablation procedures in the European pediatric population in order to improve the management of this subset of patients.
The purpose of this study is a feasibility study for the Rhythmia Medical Mapping System and Mapping Catheter on patients undergoing catheter ablation procedures for the treatment of cardiac tachyarrhythmias.
Frequent monomorphic premature ventricular complexes (PVCs) may cause a cardiomyopathy (CMP) that is reversible by suppression of the ectopic focus. This study investigates whether PVC suppression therapy can improve cardiac function and clinical condition of patients with idiopathic or ischemic CMP and frequent monomorphic PVCs. For this purpose, patients will be randomized to either one of two treatment strategies: 1) conventional heart failure therapy plus PVC suppression therapy, consisting of RFCA as primary treatment and Amiodarone as secondary treatment in case of unsuccessful RFCA, or 2) conventional heart failure therapy without PVC suppression therapy.
The purpose of the study is to analyze the different patient profiles implanted with an Implantable Cardiac Defibrillator (ICD) in Spain (guidelines adoption) and the patient prognosis as a function of clinical profile, implant indication, arrhythmias incidence, treatments or device programming.
The aim of the study is to characterize and quantify the relative effectiveness and contribution of implantable cardioverter defibrillator (ICD) therapy to the clinical outcomes under the conditions of daily practice. Swiss, multicenter, prospective, observational study.
The potassium value is important to prevent cardiac arrhythmias and sudden cardiac death. In patients with renal failure, the potassium value is not stable and tends to raise. Until now there are no data available if the potassium value has a circadian rhythm and if there are individual changes from day to day.
To describe the clinical indications for Reveal XT in diagnosis and continuous monitoring of arrhythmia and to explore the clinical applications and outcome of arrhythmia monitoring on patient care.
Feasibility study to evaluate CARTO™ XP EP Navigation System V9 and SOUNDSTAR 3D Diagnostic Ultrasound Catheter.
The objective of this study is to demonstrate that frequent atrio-ventricular (AV/PV) and inter-ventricular (V-V) delay optimization using QuickOpt in patients with cardiac resynchronization therapy device results in improved clinical response over standard of care (i.e. empiric programming or one-time optimization using any non-intracardiac electrogram optimization methods).
