Filter by:To assess the efficacy of dronedarone versus placebo for the maintenance of normal sinus rhythm after electrical, pharmacological or spontaneous conversion of atrial fibrillation/atrial flutter (AF/AFL). To assess the efficacy of dronedarone versus placebo on AF/AFL-related symptoms. To assess the efficacy of dronedarone versus placebo on ventricular rate control in case of AF/AFL recurrence.
To assess the efficacy of dronedarone versus placebo for the maintenance of normal sinus rhythm after electrical, pharmacological or spontaneous conversion of atrial fibrillation/atrial flutter (AF/AFL). To assess the efficacy of dronedarone versus placebo on ventricular rate control in case of AF/AFL recurrence. To assess the efficacy of dronedarone versus placebo on AF/AFL-related symptoms.
Patients complaining of tachycardia but with a negative Holter ECG, are for a limited time period offered a simplified electrophysiological(EP) examination. By a full electrophysiological study(EP study)electrodes are introduced for pacing and sensing i all four heart chambers. Where as by the mini invasive EP study only one electrode is introduced to the right atrium. The simplified procedure represent a smaller risk of complications, requires less resources but should yield the same diagnoses in more than 90% of the cases. The study is a feasibility study to see if the procedure can discover arrythmias in a fairly unselected patient population.
Double blind study to evaluate the efficacy and tolerability of SSR149744C and select a dose to be further investigated in the maintenance of sinus rhythm after electrical, pharmacological or spontaneous conversion of AF/AFL.
Double blind study to assess versus placebo the efficacy of SSR149744C for the conversion of atrial fibrillation/flutter to sinus rhythm at the time of the planned electrical cardioversion.
The purpose of this study is to investigate whether fish oils may be of benefit to patients with certain heart rhythm disturbances called atrial fibrillation and atrial flutter. Atrial fibrillation and atrial flutter are two heart conditions that can be successfully treated in the hospital by an ablation (in the case of atrial flutter) or a cardioversion (in the case of atrial fibrillation). Ablation involves the application of high frequency energy waves to a particular spot in the heart. Cardioversion involves resetting the heart back to a normal rhythm with the use of an electric current. Fish oil supplements may be of benefit to patients with heart problems. Recent evidence suggests that fish oils may benefit those with rhythm disturbances.
The purpose of this study is to assess the safety and effectiveness of the CONTAK RENEWAL 4 AVT device.
To assess the efficacy of dronedarone in preventing cardiovascular hospitalization or death from any cause in a population of high-risk patients with atrial fibrillation/atrial flutter (AF/AFL). To assess that dronedarone is well tolerated in this population.
Atrial fibrillation is an abnormal heart beat that starts in the upper parts of the heart and can cause stroke or death, if untreated. In general, treatments are not very effective, with frequent relapses of the abnormal heart beats. One explanation for the high relapse rate is that the treatments might not address the underlying cause of atrial fibrillation. Recently, the investigators have found that atrial fibrillation is associated with increased oxidative stress. This is a condition where abnormal oxygen forms are produced. These forms harm the cells of the heart, causing them to beat abnormally. The investigators have found increased oxidative stress in pig and mouse models of atrial fibrillation. They would like to see if oxidative stress is present in humans with atrial fibrillation. In this study, they will compare blood markers of oxidative stress between patients with and without atrial fibrillation. It is the expectation that participants with atrial fibrillation will have more abnormal blood markers of atrial fibrillation. This study requires participants to visit their doctors, undergo a history and physical examination, and give blood only once.
The purpose of this study is to demonstrate the ability of tedisamil to convert atrial fibrillation or flutter into normal sinus rhythm (NSR) in female patients.
