Comparison of Prone Position and Standard Electrocardiogram in COVID-19 Patients

COVID-19 Acute Respiratory Distress SyndromeCardiovascular Diseases2 more

Prolonged prone position ventilation reduces the 30-day mortality in acute respiratory distress syndrome (ARDS) and in COVID-19 infection. A large number of patients with COVID-19 suffered from new-onset cardiac disease, therefore, ECG is crucial. However, there is limited data on the effects of prone position on the ECG in COVID-19 patients.

An Observational Post-marketing Study Using Commercially Approved Biosense Webster (BWI) Medical...

Cardiac Arrhythmias

The purpose of this study is to prospectively collect clinical data evaluating the ongoing safety and performance during routine-use standard cardiac arrhythmia mapping and/or ablation procedures while using commercial Biosense Webster Inc. (BWI) medical devices. Data generated from the study will be used to confirm safety and performance of BWI medical devices in the marketed phase and to expand the body of evidence on the use of these devices and techniques in treatment of cardiac arrhythmias.

Evaluation of Electrocardiographic Measurements by High Density Electrode ECG (ECG-HD)

Ventricular Arrhythmias

Cardiac electrical activity is detected on the body surface with conventional electrocardiography involving 12 leads (ECG 12). A limitation of the current ECG technique is that recordings are obtained from only 6 independent precordial leads pairs ; which may miss cardiac potentials from spatially limited regions. More extensive sampling of the body surface may contribute to additional clinical information. The present study investigates the additional sensitivity of ECG using 128 body surface leads (High Density (HD) ECG) in measuring global or regional cardiac activity.

Electrocardiography for the Automatic Analysis of Arrhythmia in Children

Arrhythmia in Children

The project is a direct response to the identified lack of ECG diagnostic solutions dedicated to children. There are several tools for automatic ECG signal analysis in adults, but these cannot be used in the diagnosis of heart disorders among children. A digital ECG analysis technology developer, Cardiomatics, and the Medical University of Warsaw team have taken the challenge of developing an internationally innovative tool for automatic assessment, analysis, and interpretation of electrocardiographic signals in pediatric patients. The developed tool will allow cardiac arrhythmias in children to be assessed more effectively and minimize the time needed for cardiologists to evaluate data received from the Holter monitor due to the use of algorithms, which are based on artificial intelligence.

A Study to Evaluate the Effect of Vagus Nerve Stimulation in Patients Undergoing VT Ablation

ArrhythmiaVentricular Tachycardia (VT)

Vagus nerve stimulation (VNS) has been shown to be beneficial in multiple studies including heart failure. The goal of this clinical investigation is to gain additional information about how vagus nerve stimulation relates to abnormal heart rhythms. The outcomes of this study will help researchers design new therapies for patients that have complex and life-threatening ventricular arrhythmias.

Incidence and Morbidity of Cardiac Rhythm Disorders in Patients Assisted by ECMO-VA for Refractory...

Cardiac Rhythm Disorder

Brief Summary : Rhythm disorders are a frequent and potentially serious complication of critical patients in the ICU and postoperative cardiac surgery. In particular, atrial fibrillation (AF) is the most common rhythm disorder in patients admitted to the ICU and is associated with excess mortality during acute circulatory failure. In postoperative cardiac surgery, AF affects 15 to 45% of patients. In addition to hemodynamic effects, AF increases the risk of stroke, bleeding, respiratory or renal failure, and doubles mortality at 30 days and 6 months. In the longer term, the recurrence rate of AF within 1 year after hospital discharge is about 50%. Similarly, other rhythm disorders, supraventricular or ventricular, can be life-threatening in ICU patients. While the incidence and complications of rhythm disorders are well documented during sepsis, cardiogenic shock or after cardiac surgery, there are to our knowledge no data on the frequency and complications of rhythm disorders in patients assisted by VA ECMO. The primary objective is to describe the incidence of supraventricular rhythm disorders in patients assisted by VA ECMO.

Reverse Cardiac Remodeling Among Elite Athletes After Short and Long-term Detraining

Athlete HeartArrhythmias1 more

Exercise has many well-documented effects in the prevention or treatment of disease, but recently some studies have raised awareness of the possible negative effects of too much exercise. In former elite endurance athletes, an increased risk of cardiac fibrosis and arrhythmias have been described. Whether exercise itself is the culprit remains to be explored. The right cardiac ventricle can be overloaded during long-term intense exercise, due to increased volume load and possibly an increased afterload. In a subgroub of athletes the appearance with morphological and functional changes resembling an ARVC like phenotype. Furthermore, atrial fibrillation among male middle-aged athletes is up to 5 times more common compared to age-matched non-athletes. The working hypothesis of this study is that male athletes remodel more than females and that some of thise changes are already measureable early after end of elite sporting carreer. In this prospective cohort study, of 50 elite athletes at retirement, after 3 months and thereafter yearly for five years, to determine the characteristics of remodeling of the heart focusing on the left atrial and right ventricle.

Comparative Study of the Sternal Patch System With a Conventional Holter Recorder

Cardiac ArrhythmiaSyncope

This study will be a comparison of two externally worn recording systems for documentation of cardiac arrhythmias in symptomatic patients or patients at risk for arrhythmia. Non-invasive documentation of cardiac arrhythmias can be done using the standard electrocardiogram (ECG). This has limitations given it is performed for only a 10 sec period. Alternative methods for making longer term recording have been developed. The standard device is the 24 hour 7-lead Holter monitor. Newer technology has simplified the hardware needed to make these longer term recordings, and incorporate a self-contained recording system in a patch that is applied over the patient's chest. Little is known comparing the sensitivity, specificity and recording noise / signal artifact between the older technology (standard 24-Hour Holter monitor) and the Patch electrode.
