Filter by:This study will attempt to demonstrate the effectiveness of RSD1235 in the conversion of atrial flutter (AFL) to sinus rhythm.
The trial seeks to determine if apixaban, an investigational anticoagulant (blood-thinner) is as effective as standard therapy (warfarin) in preventing stroke and systemic embolism in subjects with atrial fibrillation and risk factors for stroke.
The purpose of this study is to demonstrate the advantage of using a gold alloy tip electrode over a platinum/iridium alloy tip electrode in ablation of the cavotricuspid isthmus in patients with atrial flutter.
It is well known that atrial fibrillation (AF) and atrial flutter occur frequently after most types of cardiac surgeries.(1-4) Postoperative AF is associated with significant morbidity, longer hospital stay, and higher related costs. Currently, it is common procedure to premedicate patients with antiarrhythmic drugs for elective cardiac surgeries. Treatments such as beta blockers, Amiodarone, and electrical pacing are used to help prevent the morbidity associated with pot-operative AF.(5) Renin-angiotensin system (RAS) activation may contribute to AF. Several clinical trials have suggested that inhibitors of this system may reduce the incidence of AF.(6-12) Patients with AF are known to have increased levels of angiotensin converting enzyme (ACE) and some types of angiotensin receptors.(13-15) Data from animal studies performed by our group suggest that cardiac ACE overexpression may lead to arrhythmic ion channel changes.(16;17) Although not studied in this group yet, it would be reasonable to conclude that the use of ACE inhibitors and angiotensin receptor blockers (ARBs) would decrease the incidence of AF in post-operative patients, too
The primary objective is to provide additional corroborative safety and efficacy data for the Navistar Thermocool catheter for the treatment of subjects with typical atrial flutter (AFL).
The objective of this study is to determine if concentrations of amiodarone in fat tissue increases constantly over time during chronic treatment with this drug, and if blood concentrations reflect accurately the concentrations in fat tissue or not. This is because excessive concentrations of this drug in tissues can produce adverse effects.
This study is designed to evaluate the safety, tolerability and preliminary efficacy of vernakalant (oral) in subjects with sustained atrial fibrillation of greater than 72 hours and less than 6 months duration
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.

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.
