Active clinical trials for "Arrhythmias, Cardiac"

This is a Phase 1, prospective, multi-center, open-label, sequential dose escalation study to explore the safety, feasibility, and efficacy of a single intracoronary infusion of BNP116.sc-CMV.I1c in patients with NYHA Class III heart failure. Patients with symptomatic congestive heart failure will be enrolled until up to 12 subjects have received infusions of investigational product. All patients will be followed until 12 months post treatment intervention, and then undergo long-term follow-up via semi-structured telephone questionnaires every 6 months for an additional 24 months (+/- 30 days).

Atrial fibrillation (AF) is the most common rhythm disturbance of the heart. It can affect people of any age but usually happens as we get older. It can cause palpitations, breathlessness, lethargy, and fainting attacks. It is also associated with an increased risk of strokes. The best treatment for it at the moment involves burning or freezing (ablation) the heart muscle in a part of the heart called the left atrium. The ablation injures the heart muscle around the so-called pulmonary veins and the procedure is called a 'pulmonary vein isolation'. This procedure work in about 60% of people. The study team have found that there are nerve endings in the heart that also cause AF and have shown that ablating these nerve endings also prevents AF. These Nerve endings are known as ganglionated plexuses (GPs). The study team would now like to perform a trial in people who still have AF after the usual pulmonary vein procedure. The study team hope that ablating the nerve endings that cause AF (GPs), we will stop their AF coming back. The study team will compare this procedure to the normal approach of doing the pulmonary vein isolation again

Ablation of consecutive atrial tachycardia (AT) after ablation of atrial fibrillation (AF) or cardiac surgery can be challenging due to complex substrate and AT mechanisms. A substantial portion of patients is known to show various tachycardias and recurrences occur in a noticeable number of cases. With the availability of novel ultra-high-density mapping techniques characterization and understanding of AT mechanisms and underlying substrate can be improved. Aim of this prospective, multi-center, randomized study is to compare a standard AT ablation approach versus minimalized ablation of the clinical AT in regards to arrhythmia free survival.

The study will include patients scheduled for transvenous pacemaker- or implantable defibrillator surgery, where venous access is necessary for lead implantation. A 1:1 randomization will be performed to either standard access (at the discretion of the surgeon) or ultrasound-guided using a wireless vascular transducer (Siemens Freestyle). Primary outcome is mean time to vascular access. In addition, success rate, complication rate and total procedure time will be measured.

Patient-centered novel e-health technology and services will lay the foundation for future healthcare systems and services to support health and welfare promotion. Yet, there is a lack of ways to incorporate novel technological innovations into easy-to-use, cost-effective and low workload treatment. The detection of atrial fibrillation (AF) paroxysms and its permanent form as well as the prevention of AF-related strokes are major challenges in cardiology today. AF is often silent or asymptomatic, but the risk of ischemic stroke seems to be similar regardless of the presence or absence of symptoms. CARE-DETECT algorithm development part I will investigate following topics: The usefulness and validity of bed sensor and mobile phone application in rhythm disorder capture compared to gold standard ECG-holter monitoring (Faros ECG) Accuracy of AF detection from PDL data Technical development of algorithms to detect arrhythmia from data collected with these novel devices Development of a pre-processing tool that will evaluate the collected data and generate a preliminary filtered report of the raw data to ease clinician's workload in data handling and rhythm evaluation. CARE-DETECT clinical trial (part II) proposal provides a new concept for low workload for healthcare personnel, high diagnostic yield in silent AF detection and AF burden evaluation. CARE-DETECT protocol proposal seeks to address following issues: Can a combination of actively used smartphone application and passive monitoring with bed sensor (with upstream ECG) - compared to routine care - enhance the detection of AF in patients who are at increased risk of stroke and have undergone a cardiac procedure? What is the actual AF burden in paroxysmal AF patients after the detection of new-onset AF? Can a direct-to-consumer telehealth with integrated cloud-based telecardiology service for medical professionals improve the efficacy of silent AF detection and what is the AF burden in patients suffering of (asymptomatic) paroxysmal AF and secondarily what is the cost-effectiveness of these new screening methods? Additionally, during the hospitalization phase of the study part II PDL data will be collected in the intervention group. PDL data will be analyzed offline with the purpose to develop new methods and will not be used to monitor treatment or for diagnosis.

This study evaluates whether a rigorously controlled high-normal level of serum-potassium (4.5-5.0 mEq/L) using dietary recommendations, potassium supplements and mineralocorticoid receptor antagonists will results in a lower incidence of cardiac arrhythmias in patients with an ICD. Patients will be randomized to this treatment or a control arm, where patients will receive usual guideline recommended follow-up.

The present project aims to investigate if the empagliflozin has an antiarrhythmic action. Analyzing the T-wave heterogeneity index, a new electrocardiographic risk marker associated with the prediction of cardiovascular risk, in diabetic patients and coronary artery disease, the investigators will verify if empagliflozin is associated with a reduction in electrical instability.

Subjects will be consented to wear the AleriTM sensor prior to, during, and after an Electrophysiology Procedure. During this time, the system will measure the following parameters from subjects: HR, temperature, saline volume/rate, urine production volume, USG, BPO. Data will be retrospectively analyzed to determine if the system effectively operates under these conditions, and can effectively monitor hydration levels of subjects compared to currently available methods.

The primary objective of the study is the development of a mathematical model for predicting potassium kinetics during and after the dialytic session. The secondary objectives of the study are: the definition of a correlation between the kinetics of intra and extra-cellular concentrations of potassium during and after the dialytic session and the onset of arrhythmias; the use of the mathematical model to modify the blood concentration of potassium by acting on the composition of the dialysis bath in order to minimize the risk of onset of arrhythmias during and after dialysis.

This study will verify the 1-channel patch-type ECG's arrhythmia diagnostic concordance rate and electrocardiogram measurement performance in pediatric patients by collecting ECG signals from patch-type ECG and Holter device simultaneously for data analysis.
