Active clinical trials for "Arrhythmias, Cardiac"

Study on the role of a combination of nutraceuticals (Ritmonutra) with an effect on benign supraventricular and ventricular extrasystoles in subjects free of a specific organic heart disease. It has been suggested treatment with a nutritional supplement, able to normalize the 'cardiac electrophysiology' and help to maintain wellness. Ritmonutra ® is a combination of nutraceuticals®, including Omega-3 polyunsaturated fatty acids, Hawthorn, Astaxanthin and Vitamin E, help to normalize the heart pacing, reducing the total number of benign extrasystoles and consequently improving the quality of life.

Monophasic action potential (MAP) recording plays an important role in a more direct view of human myocardial electrophysiology under both physiological and pathological conditions. The MAP method represents a very useful tool for an electrophysiological research in cardiology. Its crucial importance lies in the fact that it enables the study of the action potential (AP) of myocardial cell in vivo and, therefore, the study of the dynamic relation of this potential with all the organism variables what can be particularly helpful in the case of arrhythmias. Hundred and fifty patients will be included to explore mapping capabilities in cardiac chambers in patients suffering from regular or fibrillating tachycardia's with the following inclusion plan: i) Atrial fibrillation at a total of 50 patients ii) Ventricular fibrillation or patients at high risk of sudden cardiac death at a total of 50 patients iii) Junctional tachycardia at a total of 50 patients. We will focus on cardiac activation (depolarization and repolarization) in this population.

The goal of the pilot study is to compare conventional antibiotic therapy to an aggressive antibiotic therapy plan for the prevention of arrhythmia device infection in high-risk patients undergoing arrhythmia device procedures. All antibiotics are approved for use and readily available.

The objective of the SOFA trial is to investigate whether supplemental intake of n-3 polyunsaturated fatty acids (n-3 PUFA) from fish oil can reduce the recurrence of life-threatening ventricular arrhythmias in patients with an implantable cardioverter defibrillator (ICD).

The purpose of this study is to verify the effectiveness and safety of the Huawei Device software (ECG APP), which can be used to analyze, store and display the ECG data transmitted by the single-lead ECG acquisition device. The software can be used for the analysis of sinus rhythm, atrial fibrillation, and premature beats(ventricular premature beats and atrial premature beats) in adults.

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.

The overall aim of this trial is to determine the most cost effective approach to diagnose paroxysmal atrial fibrillation (PAF) following transient ischemic attack (TIA) and stroke. A summary of the rationale for this study is as follows: Recently completed randomized trials of cardiac monitoring following stroke have established that PAF is more common than previously recognized in cryptogenic stroke. The majority of TIA/stroke patients will have at least one potential stroke mechanism identified by the time etiologic investigations completed. Detecting PAF in patients with strokes with known causes (eg. lacunar and large vessel atherosclerosis) is clinically important since appropriate anticoagulation for AF reduces stroke recurrence in all patients with prior TIA/stroke not just cryptogenic strokes. There are competing technologies for evaluating cardiac rhythm and diagnosing AF but no cost effectiveness data The rates of PAF in strokes with known causes (SKC) have not been well characterized. PER-DIEM is a pilot study to compare two different cardiac monitoring technologies as first-line investigations to detect PAF in patients with recent stroke and TIA. The study will also assess whether a pivotal trial is feasible and warranted. The principal research questions to be addressed in this study will be: Whether implantable loop recorder (ILR) plus remote monitoring will diagnose more paroxysmal AF / atrial flutter and provide a better assessment of the total burden of AF resulting in a greater proportion of patients started on an OAC versus the external loop recorder (ELR) strategy. What is the relative cost-effectiveness as a first-line investigation of long-term implantable ECG (ILR) coupled with remote monitoring for 12 months compared to external event-triggered ECG loop recorder (ELR) for 30 days in the diagnosis clinically actionable AF in following TIA/stroke. 2) What is the feasibility, patient compliance, diagnostic accuracy and rates of AF detection (>30 seconds) of ILR compared to the ELR strategies.

This study investigates if the early detection and treatment of supraventricular arrhythmia (SVA) may help to prevent the progression of the arrhythmia and improve the clinical outcome. The primary endpoint investigates the delay to implement treatment in two groups of patients : Active group: Patients followed by telecardiology. Control group: Patients followed in the conventional manner. It is assumed that the delay to implement treatment will be higher in the Control group.

The goal of this clinical research study is to compare the effects of sodium bicarbonate to normal saline when used for clearing mucus blockage in patients with airway stents.

This is a study of GAP-134, an antiarrhythmic di-peptide. This study will provide an initial assessment of the safety, tolerability, and pharmacokinetics (PK) of GAP-134 after administration of ascending single intravenous (IV) doses to healthy Japanese male subjects.
