Safety of Local Dental Anesthesia in Patients With Cardiac Channelopathies

Patients of Heart Institute of the University of So Paulo with inherited cardiac channelopathies will be included, considering the criteria for inclusion and non-inclusion, after reading and signing the informed consent. They will undergo dental restorative treatment in two sessions, in the morning period, with an interval of at least ...

Phase N/A

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 ...

Phase N/A

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 ...

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 ...

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

SI + CC Versus 3:1 C:V Ratio During Neonatal CPR

Research question In newborn infants requiring CPR, does CC superimposed by sustained inflation compared to 3:1 compression to ventilation ratio improves return of spontaneous circulation? Overall objective: CC superimposed by sustained inflation will improve short- and long-term outcomes in preterm and term newborns. Hypothesis to be tested Primary hypothesis: By ...

Phase N/A

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

Avoid Transvenous Leads in Appropriate Subjects

The purpose of the study is to compare standard, single chamber transvenous ICD to sub-cutaneous ICD in occurrence of perioperative and long term device related complications and failed appropriate clinical shocks and arrhythmic death.

Phase N/A

Pathophysiology of Orthostatic Intolerance

The purpose of this study is to describe the mechanism of orthostatic intolerance, relying on cardiovascular physiological studies. The syndrome is of undetermined etiology, but the syndrome causes impairment of a number of young adults, females more than males, with symptoms of tachycardia, fatigue, lightheadedness, palpitations, blurred vision, chest discomfort, ...
