Active clinical trials for "Arrhythmias, Cardiac"

Life expectancy of children with congenital heart disease (CHD) has increased dramatically during the past years, due to the successes of cardiac surgery. Nearly all of these children with CHD can be operated at young age and more than 90% reach adulthood. However, many adults with CHD are life-long affected by cardiac events, particularly arrhythmias and heart failure, putting them at risk of premature death. These events have a large impact on quality of life of patients and their families and merit life-long hospital visits in a medical center specialized in adult CHD. Especially for adults with CHD patient care with a smartphone is suited because of their young age and chronic condition. So far, data are lacking on smartphone interventions in patients with CHD.

This is a hypothesis testing study, the hypothesis being that dietary supplements of n-PUFAs concentrates are anti-arrhythmic in ventricular arrhythmic substrates. Study Aims: To investigate whether dietary supplements of n-3 polyunsaturated fatty acid concentrates (2g PUFAs/day, Omacor) reduces MTWA (a surrogate endpoint for ventricular arrhythmia substrate) in patients with ICDs for malignant ventricular arrhythmias.

The purpose of this study is to test the feasibility of trials that change the dialysis ultrafiltration rate (UFR) by limiting the maximum rate and to estimate the extent to which limiting the ultrafiltration rate reduces the risk of abnormal heart rhythms in people with kidney failure who are being treated with chronic hemodialysis.

The aim of this study is to investigate the association between hypoglycemia, glycemic variability and cardiac arrhythmias in patients with diabetes Type II (T2D) already implanted with implantable cardiac defibrillator (ICD) and monitored remotely through Bluetooth technology and CGM (continuous glucose monitoring).

To determine whether the administration of test article will decrease the occurrence of ventricular arrhythmias in patients who have acute coronary syndrome (unstable angina, ST segment elevated myocardial infarction or myocardial infarction without ST elevation).

The objective of this study is to evaluate myocardial injury, if any, as quantified by cardiac markers (Troponin-T) in defibrillation threshold (DFT) testing during implantation of implantable cardioverter defibrillators (ICDs) using the upper limit of vulnerability (ULV) method vs. standard defibrillation threshold method.

Prospective non-randomized, single arm trial to further evaluate the safety and performance of EpiAccess, the study device, for gaining access to the normal, non-distended pericardial space during epicardial diagnostic or therapeutic (ablation) procedures.

The new BIOTRONIK implantable cardioverter defibrillator (ICD) family Lumax 540 is capable of measuring the intrathoracic impedance on a daily basis and transmission of impedance trend data via the Home Monitoring technology. In future, this will allow for automatic early detection of imminent decompensation at a presymptomatic stage and immediate initialization of clinical meaningful therapeutic interventions preventing heart failure related hospitalizations. The aim of this investigation is to record long-term impedance trends in heart failure patients with and without heart failure related events (hospitalizations due to acute decompensation) in order to develop algorithms for device-based early detection and warning of HF deterioration accompanied by pulmonary congestion.

The overall purpose of this study is to test the effects of a nurse managed psychoeducational intervention, consisting of symptom management training (SMT) and cognitive-behavioral intervention (CBI), during the first year after ICD implantation using a 3 group randomized clinical trial.

The REFLEx Study will evaluate if ENDOTAK RELIANCE G defibrillation leads with GORE ePTFE-covered coils are as good as or better than other comparative commercially available defibrillation leads with respect to electrical performance and termination efficacy in spontaneous tachyarrhythmic episodes.
