Multicentre Investigation of Novel Electrocardiogram Risk Markers in Ventricular Arrhythmia Prediction

This is a prospective open label single blinded multi-centre observational study involving a study group of patients already undergoing implantable cardioverter-defibrillator (ICD)(including Cardiac resynchronisation therapy device (CRT-D)) implant. A standard 30-minute electrophysiological (EP) cardiac stimulation protocol will be performed at the end of the ICD implant at baseline. This EP ...

Phase N/A

Correlation of the Arrhythmia Mechanism and Substrate to Ablate Persistent Atrial Fibrillation Study

Pulmonary vein isolation catheter ablation for the treatment of persistent AF (PeAF)or longstanding persistent AF is associated with success rates of 40-50% at one year. Experimental models have shown that AF results in progressive structural changes due to electrical atrial remodeling, where AF burden correlates with atrial fibrosis. The optimal ...

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 ...

Phase N/A

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 ...

Phase N/A

SJM Brady MRI Post Approval Study

This is a prospective, multi-center clinical study designed to evaluate the long-term safety of the Tendril MRI lead implanted with any SJM Brady MRI pacemaker or similar model (SJM Brady MRI system) in subjects with a standard bradycardia pacing indication through 60 months of follow up. Additionally, the study will ...

Phase N/A

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 ...

Phase N/A

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 ...

CyberHeart's Cardiac Arrhythmia Ablation Treatment: Patients With Refractory Ventricular Tachycardia/Fibrillation

This study is a prospective, multi-center (2), single arm, open label US-based feasibility study. The clinical hypothesis for the study is that the CyberHeart treatment approach will be safe and with further study will not be shown to be inferior to current treatment options, may lead to a survival benefit ...

Phase N/A

Internet-delivered Cognitive Behavior Therapy for Atrial Fibrillation

Atrial fibrillation (AF) is the most common cardiac arrhythmia (irregular heartbeat) affecting 3% of the population. AF is associated with poor quality of life (QoL) and large costs for society. In a considerable proportion of patients, AF symptoms (e.g., palpitations, fatigue, and chest pain) are not alleviated by current medical ...

Phase N/A

Discrimination of P and T Waves With Linq and Holter

Pilot Study of 20 prospective cardiology patients with loop recorders currently implanted for standard clinical indications. Eligible Subjects will be brought into the office of John Wilson, MD or Marshall Winner, MD. After informed consent is obtained from Hatton Research Staff the following will be performed subjects will have an ...
