Filter by:The primary purpose of this study is to improve the quality of Magnetic Resonance Imaging in patients with heart arrhythmia. Investigators will recruit 105 patients with arrhythmia and 30 control volunteers over 3 years and will use two arrhythmia-tolerant imaging methods for diagnosis.
The purpose of this study is to see if some people with postural tachycardia syndrome (POTS) have higher levels of immune proteins (autoantibodies) directed against receptors of the autonomic nervous system, and if these autoantibodies make a difference in their POTS symptoms. The investigators also want to see if the levels of these autoantibodies stay the same over time.
To evaluate the use of an occlusion balloon (Bridge™ Occlusion Balloon, Spectranetics) within the Superior Vena Cava in lead extraction patients.
This is an observational, prospective, non-randomized, multicenter, post approval study being conducted in the United States, Europe and Asia-Pacific Regions.
The primary objective of this study is to evaluate whether, in patients with first-ever atherothrombotic or lacunar stroke without any previous history of atrial fibrillation (AF)/atrial flutter (AFL)/atrial tachycardia (AT), the detection of AF/AFL/AT (silent or symptomatic) by using a continuous cardiac rhythm monitoring with implantable loop recorder (ILR) during the first 12 months of observation is higher than the detection by using a standard cardiac monitoring (physical exam, 12-lead electrocardiogram [ECG] at baseline, 3, 6, and 12 months and Holter ECG at 3 months) in the same period of time.
With the increasing aging population demographics and life expectancies, the number of very elderly patients undergoing surgery is rising. Elderly patients constitute an increasingly large proportion of the high-risk surgical group. Cardiac complications and postoperative pulmonary complications are equally prevalent and contribute similarly to morbidity, mortality, and length of hospital stay. Specific optimization strategy of general anesthesia has been tested in high-risk patients undergoing major surgery to improve outcomes. Our hypothesis is that a combined optimization strategy of anesthesia concerning hemodynamic, ventilation, and depth of anesthesia may improve short- and long- term outcome in elderly undergoing high risk surgery.
This Study is designed to determine the outcome and effect of implementation of Esophageal Stylet as a strategy to minimize the risk of esophageal injury during the atrial fibrillation catheter ablation procedure.
Background: Arrhythmia recognition is a fundamental skill for the provider of advanced life support (ALS). Acquire it is difficult, leading to the birth of systematic methods in an attempt to simplify and optimize, however, it has not compared the effectiveness among the three methods with more evidence among professionals with varying degrees of medical training (ALS Workshop participants). Objective: To determine and compare the effectiveness of the three most widespread and with more evidence systematic methods (10, 6 and 4 steps) for the recognition of arrhythmias in a short-term and its perceived easiness among ALS workshop participants. Methods / design: Educational Cuasi experimental trial with pre and post intervention measurement, blind, with randomized allocation, in 84 ALS workshop participants. Three systematic methods to recognize arrhythmias will be taught and their effectiveness to diagnose in a short-term and its perceived easiness will be measured and compared.
The objective of this clinical investigation is to evaluate: 1. the safety and efficacy of the CyberHeart System, CardioPlan™ Software and Laptop, in treating patients with refractory ventricular tachycardia (VT) using the CyberKnife® Radiosurgical System. 2. The CyberHeart System performance with respect to the ability to contour myocardial targets that are transferred to the Multi-plan® Treatment Planning Software of the CyberKnife® system for the production and delivery of a safe radiosurgical treatment plan. Cardiac radiosurgery is a minimally-non invasive, painless, procedure. Tissue ablation can be accomplished precisely.
This study aims at recording cardiac arrhythmias in patients after open heart surgery. The arrhythmias will be monitored during the entire first postoperative period, till six weeks after surgery.
