Internet-delivered Cognitive Behavior Therapy for Atrial Fibrillation

Atrial fibrillation (AF) is the most common cardiac arrhythmia (irregular heartbeat) affecting 3% of the population. AF is associated with poor quality of life (QoL) and large costs for society. In a considerable proportion of patients, AF symptoms (e.g., palpitations, fatigue, and chest pain) are not alleviated by current medical ...

Phase N/A

Diabetic Retinopathy: Effects of Melatonin Treatment on Visual Functions and Circadian Rhythm

This study evaluates the effect of melatonin 4 mg on circadian rhythm and visual function of patients with diabetes mellitus. Half of the patients will receive melatonin (arm-1) and the other half will receive placebo (arm-2), both groups in 3 weeks. After a week of washout, the patients will cross ...

Discrimination of P and T Waves With Linq and Holter

Pilot Study of 20 prospective cardiology patients with loop recorders currently implanted for standard clinical indications. Eligible Subjects will be brought into the office of John Wilson, MD or Marshall Winner, MD. After informed consent is obtained from Hatton Research Staff the following will be performed subjects will have an ...

Phase N/A

Real Zero Fluoroscopy Catheter Ablation.

Catheter ablation is a well-established treatment to treat patients with a wide scope of heart arrhythmias. The study is an investigator-initiated, retrospective analysis of prospectively collected data. The study population consists of patients with right-sided arrhythmias who underwent zero-fluoroscopy catheter ablation between the years 2016 and 2018 in 3 centers ...

Phase N/A

Physical Activity and Pacemaker Study

The benefits of habitual physical activity (PA, activities of at least moderate intensity defined as 3 metabolic equivalents (METs)) are well-recognized. Emerging information from large data sets strongly suggest high levels of sedentary behavior, defined as activities <1.5 METs (equivalent to the amount of energy expended during seated activities such ...

Phase N/A

The Rhytmia System to Determine the Precise Location and Potential Mechanism of Premature Contractions

This is a purely observational study. No special methodology choice, no comparison. The study want to find the determination of precise location of the focus and mechanisms involved constitutes a challenge for conventional electrophysiology, even with tridimensional systems, because of the time needed for accurate delineation of the location (due ...

Phase N/A

Antiarrhythmic and Cardioprotective Effects of Atorvastatin Versus Magnesium Sulfate in Cardiac Valve Replacement Surgery

Arrhythmia is a common complication after cardiac valve surgery. Postoperative atrial fibrillation (POAF) is the most common type of arrhythmia after cardiac surgery. It has different leading causes, including myocardial injury, inadequate myocardial protection, the effect of cardiopulmonary bypass, and electrolyte imbalance. Beta blockers, amiodarone, and magnesium sulfate are used ...

Phase

Autoimmune Basis for Postural Tachycardia Syndrome

Postural tachycardia syndrome (POTS) is a debilitating disorder resulting from cardiovascular autonomic dysfunction, has many causes and is very difficult to treat effectively. The investigators have identified the presence of autoantibodies (immune proteins) directed against some receptors of the autonomic nervous system that can cause patient's symptoms on standing. The ...

EASYER (EpiAccess SYstem Registry) A Post Market Observational Registry

The Registry will be a prospective non-randomized single-arm trial of up to 150 patients enrolled in up to ten (10) centers in the United States. The overall duration of the registry is estimated to be 18 months per site. For the patients the registry duration will be from the time ...
