Filter by:The purpose of this study is to determine whether performing active compression decompression cardiopulmonary resuscitation (ACD-CPR) with an impedance threshold device (ITD) compared to conventional standard cardiopulmonary resuscitation (S-CPR) will impact the neurologic recovery and survival to hospital discharge following out-of-hospital cardiac arrest.
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.
Sudden cardiac death is a tragic event that strikes all age groups and is unfortunately increasing in prevalence. Because it is difficult to predict those at highest risk, this study is designed to test the hypothesis that new imaging techniques (magnetic resonance imaging [MRI] and computed tomography [CT]) are useful for identifying factors which put people at high risk for sudden death.
Sudden cardiac death is in most cases triggered by ischemia-related ventricular tachyarrhythmias and accounts for 50% of deaths from cardiovascular disease in developed countries. Chronic elevation of indicators of coagulation activation has been found in patients with coronary heart disease , but a role of coagulation activation and proinflammatory state as a potential risk factor for ventricular fibrillation (VF) during acute myocardial infarction has not been investigated.
The Medtronic InSync III Marquis Cardiac Resynchronization Therapy Defibrillator (CRT-D)-System (implantable cardioverter-defibrillator with biventricular stimulation for cardiac resynchronization) is equipped with the "Conducted-Atrial Fibrillation (AF)-Response-Algorithm (CAFR)". This algorithm is designed to maximize biventricular stimulation and thus the amount of cardiac resynchronization when atrial fibrillation occurs. The goal of the study is the evaluation of the effect of the CAFR in CRT-patients suffering from atrial fibrillation by quantification of the increase of biventricular pacing during atrial fibrillation caused by CAFR as well as the influence of the CAFR on the ventricular heart rate.
This is a prospective multicentric Italian study to evaluate the arrhythmic risk in myotonic dystrophy type 1.
To investigate the relationship between the use of prescription drugs and the occurrence of ventricular arrhythmia and sudden death.
To evaluate whether genetic variation in selected candidate genes is associated with risk of sudden cardiac death in the general population.
To compare home use of an automatic external defibrillator (AED) to the use of local emergency medical system in treating survivors of sudden cardiac arrest.
To evaluate whether T Wave Alternans can predict ventricular arrhythmias and sudden cardiac death (SCD) in a prospective epidemiologic natural history study. The prospective epidemiologic pilot study included 550 patients that had left ventricular dysfunction and no history of sustained ventricular arrhythmias. The primary hypothesis tested was whether there was an increased risk of having an arrhythmic event when T Wave Alternans was present in the patient. The secondary aims included comparing risk due to T Wave Alternans between the ischemic patients and non-ischemic patients and assessing whether T Wave Alternans remained an independent predictor of risk upon adjustment for other known risk factors for arrhythmic events such as ejection fraction, ventricular ectopy, NSVT, average NN interval, and RR interval variability. The study approach was a standard epidemiologic surveillance technique. The subject population consisted of individuals with Class I to III heart failure who will underwent a TWA and Holter monitor test and then were followed for up to two years or until arrhythmic events occured.
