Chronic ventricular pacing in children: toward prevention of pacing-induced heart disease
In children with congenital or acquired complete atrioventricular (AV) block, ventricular pacing is indicated to increase heart rate. Ventricular pacing is highly beneficial in these patients, but an important side effect is that it induces abnormal electrical activation patterns. Traditionally, ventricular pacemaker leads are positioned at the right ventricle (RV). The dyssynchronous pattern of ventricular activation due to RV pacing is associated with an acute and chronic impairment of left ventricular (LV) function, structural remodeling of the LV, and increased risk of heart failure. Since the degree of pacing-induced dyssynchrony varies between the different pacing sites, ‘optimal-site pacing’ should aim at the prevention of mechanical dyssynchrony. Especially in children, generally paced from a very early age and having a perspective of life-long pacing, the preservation of cardiac function during chronic ventricular pacing should take high priority. In the perspective of the (patho)physiology of ventricular pacing and the importance of the sequence of activation, this paper provides an overview of the current knowledge regarding possible alternative sites for chronic ventricular pacing. Furthermore, clinical implications and practical concerns of the various pacing sites are discussed. The review concludes with recommendations for optimal-site pacing in children
Congenital and childhood atrioventricular blocks: pathophysiology and contemporary management
Atrioventricular block is classified as congeni-
tal if diagnosed in utero, at birth, or within the first
month of life. The pathophysiological process is believed
to be due to immune-mediated injury of the conduction
system, which occurs as a result of transplacental pas-
sage of maternal anti-SSA/Ro-SSB/La antibodies.
Childhood atrioventricular block is therefore diagnosed
between the first month and the 18th year of life.
Genetic variants in multiple genes have been described
to date in the pathogenesis of inherited progressive car-
diac conduction disorders. Indications and techniques of
cardiac pacing have also evolved to allow safe perma-
nent cardiac pacing in almost all patients, including
those with structural heart abnormalities

A photo management system for future home environments
In future home environments, users will have access to their digital assets on any device in any room. Home environments will have a high degree of hardware, middleware, software and administrative heterogeneity. Current protocols and systems do not address the consistency problem of mobile data in heterogeneous environments. When data are distributed and duplicated, their logical identities are lost. We propose the introduction of logical identities of mobile data and idcntitypreserving data exchange. We designed the Universal Resource Access Protocol (URAP) and validated it in the MemorySafe system, an experimental photo management system for future home environments. In this paper, we present the proposed concepts and the URAP protocol. We show how they are used to address the consistency problem of mobile data in the MemorySafe system

On the Relation Between Unity Properties and Sequences of States
Stepwise refinement of programs has proven to be a suitable method for developing parallel and distributed programs. We examine and compare a number of different notions of program refinement for Unity. Two of these notions are based on execution sequences. Refinement corresponds to the reduction of the set of execution sequences, i.e. reducing the amount of nondeterminism. The other refinement notions are based on Unity properties as introduced by Chandy and Misra. The Unity approach is to refine specifications. Although it has proven a suitable formalism for deriving algorithms, it seems less suitable for handling implementation details. Following Sanders and Singh, we formalize program refinement in the Unity framework as the preservation of Unity properties. We show that Unity properties are not powerful enough to characterize execution sequences. As a consequence, the notion of property-preserving refinement differs from the notion of reducing the set of execution sequences. Keyw..
