BACKGROUND This study evaluated the wearable cardioverter-defibrillator (WCD) for use and effectiveness in preventing sudden death caused by ventricular tachyarrhythmia or fibrillation. METHODS From April 2010 through October 2013, 6043 German WCD patients (median age, 57 years; male, 78.5%) were recruited from 404 German centers. Deidentified German(More)
Coupled systems of differential-algebraic equations (DAEs) may suffer from insta-bilities during a dynamic iteration. For a general dynamic iteration, we extend the existing analysis on recursion estimates, error transport and stability to a general DAE setting. In this context, we discuss the influence of certain coupling structures and the computational(More)
Sirs: Subcutaneous implantable cardioverter-defibrillators are a new therapeutic option in patients at risk for malignant ventricular tachyarrhythmias and sudden cardiac death. Recently published trials demonstrate effective sensing, discrimination and termination of spontaneous and/or induced ventricular tachycardia (VT) and ventricular fibrillation (VF)(More)
pital by the emergency physician after resuscitation in cardiac arrest due to a ventricular fibrillation (VF) caused by a non-classified cardiomyopathy with a impaired left ventricular function of about 35% and a long QT-syndrome. As a consequence of cerebral hypoxia the patient suffered from an impaired neurological status with cognitive deficit and(More)
In this paper we focus on incorporating a stochastic collocation method (SCM) into a topology optimization for a power semiconductor device with both material and geometrical uncertainties. Such geometrical and material variations, which result predominantly from lithography proximity and process imperfections, have a direct impact on its yield and(More)
BACKGROUND Accumulating evidence indicates that target temperature management (TTM) is beneficial in patients resuscitated after cardiac arrest since it appears to improve neurological outcome. However, the optimal cooling method (surface vs. intravascular) has not yet been specified. Substantial heart disease is present in most of these patients and(More)
