AV Delay Optimization vs. Intrinsic Conduction in Pacemaker Patients With Long PR Intervals

Cardiac pacing is the only effective treatment for symptomatic sinus node dysfunction. Most patients with preserved left ventricular function receive dual chamber pacemakers; however, right ventricular pacing can have detrimental effects on left ventricular function due to the abnormal electrical and mechanical activation pattern of the ventricles. Many patients receiving ...

Phase N/A

Enhanced Diagnosis of Ventricular Activation Pattern Using Intracardiac Electrograms

The objective of this study will be to evaluate the ability of IEGMs (Signal recorded from implanted pacing leads) and pseudo ECGs (derived from various IEGMs) to characterize various electrical conduction patterns. Electroanatomic mapping data and 12 Lead ECG will also be collected to characterize electrical conduction patterns during standard ...

Comparison of Alcoholic Chlorhexidine 2% Versus Alcoholic Povidone Iodine for Infections Prevention With Cardiac Resynchronization Therapy Device Implantation

In this context, all measures that will reduce the risk of infection, will improve the prognosis of these patients. Thus, recent studies have shown greater effectiveness of local preparation for alcoholic chlorhexidine (applicator containing 2% chlorhexidine and 70% alcohol isopropanolol) (AC 2%) compared to the aqueous povidone iodine (API)in general ...

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 ...

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

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 ...

Reverse RAMP Pacing to Terminate Ventricular Tachycardia ( REV-RAMP)

Cardiac pacing which involved stimulating the heart electrically with electrical wires that go into the heart is routine practice in the diagnosis and treatment of heart rhythm problems. Clinically this involved the fields of cardiac pacing and electrophysiology. Patients who are at risk of sudden death because of serious heart ...
