Dysrhythmia Clinical Trials

A listing of Dysrhythmia medical research trials actively recruiting patient volunteers. Search for closest city to find more detailed information on a research study in your area.

RESULTS

Found (74) clinical trials

Dysrhythmias are abnormal heart rhythms that can decrease the heart’s pumping effectiveness. Normally the heart beats at a rate of 60-100 times a minute. If left untreated, a dysrhythmia can lead to more serious cardiovascular problems. If you would like more information on a study concerning Dysrhythmia, please contact us ...

Phase N/A

The primary objective is to understand the role of ATP in primary prevention patients indicated for ICD therapy. The incidence of all-cause shocks in subjects programmed with shocks only will be compared with subjects programmed to standard therapy (ATP and shock) to assess equivalency. Multivariate analyses will also be performed to ...

Phase N/A

This research study is investigating a medical device called the ZOLL Short-term use Wearable Defibrillator (“SWD 1000”).  A defibrillator is a device used to control an abnormal heart beat by applying an electric current, also known as "shocking", to the chest wall or heart. We are asking you to take ...

3T MRI CIED Post-Approval Study

The purpose of this study is to evaluate product performance of Magnetic Resonance (MR) Conditional Cardiac Implantable Electronic Devices (CIED) following 3 tesla (3T) MRI exposure. This will be achieved by evaluating the changes in pacing capture threshold (PCT) measurements following 3T MRI scan exposure. This study is required by ...

AV Delay Optimization vs. Intrinsic Conduction in Pacemaker Patients With Long PR Intervals

Cardiac pacing is the only effective treatment for symptomatic sinus node dysfunction. Most patients with preserved left ventricular function receive dual chamber pacemakers; however, right ventricular pacing can have detrimental effects on left ventricular function due to the abnormal electrical and mechanical activation pattern of the ventricles. Many patients receiving ...

COMParison of Algorithms for Rotational Evaluation in Atrial Fibrillation

In this study, the investigators will analyze electrograms collected routinely at clinical electrophysiology study (EPS) in patients undergoing ablation for atrial fibrillation. These electrograms will be recorded from a variety of clinically approved catheters under standard of care conditions, and will be analyzed to better understand the mechanisms for atrial ...

Esophageal 3D Mapping System for Cardiac Arrhythmias

Background Cardiac arrhythmias are common and may have devastating consequences for affected patients. To prevent f.e. strokes due to atrial fibrillation, heart failures as a consequence of long-standing tachyarrhythmias or death due to ventricular fibrillation, accurate and timely diagnoses are essential. The standard diagnostic tool for heart rhythm disorders in ...

Phase N/A

Enhanced Diagnosis of Ventricular Activation Pattern Using Intracardiac Electrograms

The objective of this study will be to evaluate the ability of IEGMs (Signal recorded from implanted pacing leads) and pseudo ECGs (derived from various IEGMs) to characterize various electrical conduction patterns. Electroanatomic mapping data and 12 Lead ECG will also be collected to characterize electrical conduction patterns during standard ...

Phase

Clinical and Device Functional Assessment of Real World ICD Patients

For these reasons, it is very important to observe the clinical practice on a large variety of centers and countries, with the objective to collect long term safety and performance data in patients undergoing ICD/CRT-D device implantation (first implant, replacement or upgrade). The safety and performance of the ICDs can ...

Italian ClinicalService Project

ClinicalService is a project aiming to provide information and analysis of clinical and device data, back to the treating healthcare providers regarding their own patients, in order to help those healthcare providers improve outcomes and understanding of their patients' care or patients' management. The mission of the Italian ClinicalService Project ...
