The Effect of Atrial Fibrillation Hemodynamics on Regulation of Cerebral Blood Flow

This is a prospective study evaluating 10 subjects referred for elective direct current cardioversion (DCCV) of atrial fibrillation. Subjects will be seen at Parkland Health and Hospital System. After full consent is obtained and explanation of the research, each subject will undergo a series of entirely non-invasive tests including Transcranial ...

A Prospective Randomized Study Comparing Radiofrequency Energy With Cryoenergy

Transvenous pulmonary vein (PV) isolation using radiofrequency energy is an effective treatment for atrial fibrillation (1-4). However, rare but potentially life threatening complications such as thromboembolism (5), PV stenosis (5-10), left atrium-oesophageal fistula (11) and inflammatory syndromes (12) have been described. In preliminary studies an alternate approach using cryoenergy induces ...


Full Disclosure Observational Cardiac Rhythm Documentation Follow-up After Surgical Atrial Fibrillation Therapy

24 hour Holter monitoring (24HM) is commonly used to assess cardiac rhythm after surgical therapy of atrial fibrillation. This "snapshot" rhythm documentation leaves a large diagnostic window of non recorded atrial arrhythmias and as such a large amount of uncertainty in follow-up result assessment. To improve accuracy of rhythm surveillance ...

Gene Expression Profiling in Subjects With Postoperative Atrial Fibrillation After Cardiac Surgery

Atrial fibrillation is a type of irregular heartbeat that is common after having heart surgery. There may be many different reasons why some people get atrial fibrillation after their heart surgery. These reasons may include that a person is older or that he/she is taking certain types of medications before ...

Phase N/A

Low Dose of Diltiazem for Rate Control of Atrial Fibrillation

This study is to show the efficacy and safety of low dose diltiazem for the treatment of atrial fibrillation with rapid ventricular response in emergency room. We will compare the standard dose of diltiazem(0.25mg/kg) with low dose diltiazem(0.1mg/kg)in atrial fibrillation with rapid ventricular response in ED.


Intravenous Lidocaine and Postoperative Outcomes After Cardiac Surgery

Subjects undergoing cardiac surgery are randomized into one of two groups. - Group 1: Intravenous Lidocaine Group - Group 2: Intravenous placebo Group Either Lidocaine or placebo is administered throughout surgery and 24 hours after surgery. Patients in both groups will undergo quality of life assessments and functional recovery assessments ...

Phase N/A

Radiofrequency Ablation of Atrial Fibrillation Under Totally Thoracoscope

Atrial fibrillation (AF) is a common supraventricular arrhythmia, the incidence of which increases with age. The aim of treatment of atrial fibrillation is to restore sinus rhythm and return the heart to atrioventricular synchrony, avoiding the risk of thromboembolism. The fact that pharmacological therapy of AF is at best 50% ...

Does Radioiodine Treatment Prevent Atrial Fibrillation and Bone Loss in Endogenous Subclinical Hyperthyroidism?

Subclinical hyperthyroidism is defined as the presence of serum free thyroxine (T4) and triiodothyronine (T3) levels within the reference range and a reduced serum thyrotrophin (TSH) level. Evidence is accumulating that it has important clinical effects. The SUBstudy is a randomised, Dutch multicenter trial to study whether radioiodine treatment prevents ...

Phase N/A

Genetic Determinants of Warfarin Anticoagulation Effect

The response to warfarin varies greatly among individuals. Some of this variability can be ascribed to genetic polymorphisms in the gene encoding for CYP2C9, the enzyme mediating the metabolism of S warfarin. In addition genetic polymorphism in other genes (i.e. VKORC1, factor VII) have been shown to account for some ...

Genetic Study of Atrial Fibrillation: Focusing on Renin-Angiotensin System and C-Reactive Protein Genes

Multi-locus and multi-gene studies of atrial fibrillation, focusing on renin-angiotensin system genes and C reactive protein gene
