Increasing Detection of Sub-Clinical Atrial Fibrillation in Defibrillator Patients With the Use of a VDD-ICD Lead

Recipients of implantable defibrillators (ICD) are at high risk of developing both AF and stroke, given the presence of multiple cardiovascular risk factors. Oral anticoagulation can prevent most strokes in patients with AF; provided that AF is recognized before a stroke occurs. Up to about 40% of incident AF may ...

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

Heart Failure and Sudden Cardiac Death Japan Registry

The purpose of this observational registry is to collect clinical events and outcome data in 4 different study populations (cohorts), with a majority of Japanese subjects, that are at risk of sudden cardiac death (SCD) and heart failure (HF) events. These event rates will be compared with available published data ...

Phase N/A

EnSite Precision Observational Study

The EnSite Precision Cardiac Mapping System is a newly developed system that introduces features such as Delayed Enhancement Magnetic Resonance Imaging (DE-MRI) image integration, lesion marking automaticity, automatic mapping, and workflow flexibility to aid in the success of complex ablation procedures. Utilization of this system in the treatment of complex ...

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 ...

Phase N/A

Hemodynamic Differentiation of Tachycardia Episodes Using Tissue Perfusion

This study is being conducted to evaluate the feasibility to detect hemodynamic changes induced by supra-ventricular or ventricular tachycardia (SVT or VT) using tissue perfusion. Patients with a standard indication for either an electrophysiological study or an implantable cardioverter defibrillators(ICD) implant can be included into this study. Tissue perfusion and ...

Phase N/A

Efficacy Study of Sodium Channel Blocker in LQT3 Patients

LQT3 mutations in the LQTS Registry will be studied using in vitro expression studies to determine whether ranolazine causes a decrease in late sodium current, slower recovery from inactivation and/or changes in time course of inactivation, ameliorating the causative functional effect of each individual mutation. Individuals with select LQT3 mutations ...


Conduction Abnormalities With Severe Aortic Stenosis Before and After Transcatheter Aortic Valve Replacement

Each subject who fulfills the inclusion/exclusion criteria will be provided with Zio patch for 2 weeks before TAVR. Immediately after the procedure, patients will be admitted per TAVR protocol and will be on telemetry. Data about their ECGs and any arrhythmias will be collected. Upon discharge, patients will be provided ...

Phase N/A

The Response To Ajmaline Provocation in Healthy Subjects

The investigators will recruit healthy subjects without a history of cardiac symptoms or a family history of sudden death or premature arrhythmogenic cardiac disease. Participants will undergo electrocardiographic phenotype assessment with standard and high lead electrocardiogram and sodium channel provocation. Detailed cardiac structural examination will be performed with cardiac magnetic ...


Detection of Silent Atrial Fibrillation aFter Ischemic StrOke

Atrial fibrillation (AF) is associated with a high risk of stroke and its prevalence increases in subjects aged 65 years. After an ischemic stroke, the use of standard monitoring methods may underestimate the detection rate of AF. Recent studies demonstrated a fourfold to sixfold increase in the detection of AF ...
