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 ...

Fluid Responsiveness Evaluation in Patients With Acute Circulatory Failure and Arrhythmia With Atrial Fibrillation: Indice Delta ITV / Delta RR

Fluid therapy is often used as first line treatment of acute circulatory failure, aiming an increase in cardiac output (by improving preload) and in tissue perfusion. Depending on left ventricular systolic function, fluid challenge could lead to an increase in cardiac ouput and tissue perfusion, or only detrimental consequences (by ...

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 ...

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 ...

Esmolol to Treat the Hemodynamic Effects of Septic Shock

Septic shock is a leading cause of death around the world, with a mortality that often ranges 30-50% but in some locations may be even higher. Despite advances in critical care medicine over the last several decades, few therapeutic interventions have demonstrated mortality benefit in this population besides antimicrobial medications, ...

Phase

Dexmedetomidine and Fentanyl Versus Midazolam and Remifentanil for Sedation in Patients Undergoing Ablation Procedures

The role of ablation for chronic persistent AF has been debated amongst cardiologists for some time, and there is increasing evidence that ablation may be superior to medical management. As populations age, the rate of AF is likely to increase and therefore the numbers of ablations performed for this arrhythmia ...

Phase N/A

Ripple Mapping for Epicardial Mapping of Brugada Syndrome

Whether a mapping algorithm "Ripple-mapping" is able to rapidly identify the areas of long-duration multicomponent electrograms which constitute the targets for ablation for an automated strategy remains to be assessed.

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

Micra Transcatheter Pacing System Post-Approval Registry

The Micra Registry is a global, prospective, observational, multi-site registry. Patients enrolled in the Micra Registry will be prospectively followed for a minimum of 9 years post-implant or until registry closure, patient death, patient exit from the registry (i.e., withdrawal of consent), or unless patient is participating in an acute ...

Phase N/A

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 ...
