Filter by:The CASPER will collect systematic clinical assessments of patients and families within the multicenter Canadian Inherited Heart Rhythm Research Network. Unexplained Cardiac Arrest patients and family members will undergo standardized testing for evidence of primary electrical disease and latent cardiomyopathy along with clinical genetics screening of affected individuals based on an evident or unmasked phenotype.
The purpose of the Registry is to collect data on how Implantable Cardioverter Defibrillator (ICD) therapies and medications are being used by physicians to treat ventricular arrhythmias in order to better understand how to improve the clinical care of patients and effectiveness of ICD therapies.
The purpose of this study is to test specific device programming in patients without a previous history of a life-threatening, abnormally fast heartbeat who are implanted with a Medtronic ICD (Implantable Cardioconverter Defibrillator) or ICD with CRT (Cardiac Resynchronozation Therapy) device. The information learned from this study could be used to guide physicians in future ICD or CRT device programming.
The purpose of the OMNI study is to characterize therapy and diagnostic utilization in study participants implanted with study devices and to describe Implantable Cardioverter Defibrillator(ICD)therapy utilization for life threatening arrhythmias in primary and secondary prevention study participants. This study will assess therapies in Medtronic pacemaker, defibrillator, and cardiac resynchronization therapy devices. The first therapy is for reducing unnecessary pacing in pacemaker patients. The second therapy provides pacing therapy in an attempt to stop fast or life threatening ventricular arrhythmias in lieu of delivering a defibrillation shock. The third therapy is a diagnostic measurement of a patient's fluid status and provides the physician information on the patient's heart failure status. The study will also assess the time to a patient's first defibrillation shock and will verify that the shock was for a fast or life threatening ventricular rhythm.
The purpose of this registry is to collect information on the health status of patients receiving Marquis/Maximo VR Implantable Cardiac Defibrillators (ICDs), how the devices are being programmed and how this correlates to clinical patient outcome.
To investigate a potential relationship between four different classes of non-cardiovascular drugs and the risk of sudden cardiac death.
Primary objective: - to assess the efficacy of SSR149744C for the prevention of ventricular arrhythmia-triggered ICD interventions. Secondary objectives: - to assess versus placebo the tolerability of the different dose regimens of SSR149744C in the selected population. - to document SSR149744C plasma level during the study.
Sudden cardiac arrest is one of the most common causes of death in industrial countries. The main objective of this study is to built up a register of all out-of hospital resuscitation in a defined area. According to this register, it is possible to evaluate for example predictors of survival to improve training and organisation of prehospital resuscitations.
The DAVID II Clinical Study evaluates the hypothesis that, in patients needing an ICD but without overt indications for pacing, AAI pacing with maximal concomitant drug therapy will not increase the rate of the combined endpoint of mortality or hospitalization for new or worsened heart failure as compared to patients with ventricular backup pacing.
The INSURE trial is a multi-center, prospective trial to collect information about adequate ICD therapies in ICD patients before and after their first elective ICD replacement.
