Active clinical trials for "Arrhythmias, Cardiac"

Primary objective is to assess the efficacy of the new ATP Autoswitch function in simple, dual or triple chamber ICD.

The purpose of this study is to investigate the cost-effectiveness and effectiveness of remote-monitoring compared to standard care in patients with implantable cardioverter defibrillator.

We hypothesize that oral supplementation with omega-3 PUFA will decrease occurrence of arrhythmic events among post-MI, ICD recipients.

In this study a new technique for ablation in atrioventricular nodal reentrant tachycardia using cryo-energy will be studied in cases where the standard approach has higher risk.

Effects of switching from racemic methadone to R-methadone on serum methadone concentrations and QTc intervals

Atrial fibrillation (AF) is the most common cardiac arrhythmia affecting millions of people in the US and around the world. Over the last 20 years, catheter based AF ablation has been widely adopted offering improved symptom control for many patients worldwide. However, long-term success rates remain suboptimal. Prior work indicates that distal connections between coronary sinus musculature and the left atrium exist and provide a substrate for single or multiple reentry beats as a trigger for atrial fibrillation. In this trial, the investigators will examine the efficacy of elimination of distal connection(s) between coronary sinus and left atrial musculature for suppression of recurrent atrial arrhythmias.

This study is to assess the effectiveness and safety of using cryoballoon ablation comparing with anti-arrhythmic drug therapy as initial treatment for naive patients with persistent atrial fibrillation.

The effects colchicine administration for acute pericardial effusion after radiofrequency catheter ablation (RFCA) of atrial fibrillation on the recurrences of arrhythmia.

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 recent developments of research on iPS (induced pluripotent stem) cells lead to the establishment of mature cell lines such as cardiomyocytes or valvular interstitial cells with genetic and cellular characteristics of the donors. These cells represent a biological material more readily available to identify the pathophysiological mechanisms involved in the diseases of BrS or ERS patients, which will lead to the identification of genetic markers.
