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 ...

Renal Nerve Stimulation and Renal Denervation in Patients With Sympathetic Ventricular Arrhythmias

Rationale Sympathetic activity plays an important role in the pathogenesis of ventricular tachyarrhythmia. Previous studies have shown evidence of significant heritable influences on individual responses to adrenergic stimulation. Catheter-based renal sympathetic denervation (RDN) is a novel treatment option for patients with resistant hypertension, proved to reduce local and whole-body sympathetic ...

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 ...

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 ...

Phase

The Response To Ajmaline Provocation in Healthy Subjects

The investigators will recruit healthy subjects without a history of cardiac symptoms or a family history of sudden death or premature arrhythmogenic cardiac disease. Participants will undergo electrocardiographic phenotype assessment with standard and high lead electrocardiogram and sodium channel provocation. Detailed cardiac structural examination will be performed with cardiac magnetic ...

Correlation of the Arrhythmia Mechanism and Substrate to Ablate Persistent Atrial Fibrillation Study

Pulmonary vein isolation catheter ablation for the treatment of persistent AF (PeAF)or longstanding persistent AF is associated with success rates of 40-50% at one year. Experimental models have shown that AF results in progressive structural changes due to electrical atrial remodeling, where AF burden correlates with atrial fibrosis. The optimal ...

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 ...

CyberHeart's Cardiac Arrhythmia Ablation Treatment: Patients With Refractory Ventricular Tachycardia/Fibrillation

This study is a prospective, multi-center (2), single arm, open label US-based feasibility study. The clinical hypothesis for the study is that the CyberHeart treatment approach will be safe and with further study will not be shown to be inferior to current treatment options, may lead to a survival benefit ...

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 ...
