Consider a set of nodes distributed spatially over some region forming a network, where every node takes measurements of an underlying process. The objective is for every node in the network to estimate some parameter of interest from these measurements by ...
In pacing-induced models of atrial fibrillation (AF) that mimic atrial high-frequency foci, the increase in AF susceptibility over time is not paralleled by any increase in dispersion of repolarization (DOR). Measurements of effective refractory periods (E ...
Rapid pacing of atrial fibrillation (AF) can induce local capture of the atrial tissue and preliminary studies showed that the septum area was the only location allowing simultaneous capture of both atria from a single site. The present model-based study i ...
We present a model-based study of therapeutical approaches to atrial fibrillation with a focus on pacing. After a systematic evaluation of different atrial pacing sites, we selected pacing from the septum area and designed a novel septum pacing protocol fo ...
Introduction: We recently observed in human left atrium periods of intermittent 2:1 and 1:1 atrial capture, preceded by atrial repolarization alternans (Re-ALT) during rapid pacing. It remains undetermined whether Re- ALT plays a role in preventing 1:1 atr ...
Introduction: It has been shown that repolarization alternans (Re-ALT), a beat-to-beat alternation in action potential duration, enhances dispersion of repolarization DOR above a critical heart rate and promotes susceptibility to ventricular arrhythmias. I ...

The chapter describes recent developments in distributed processing over adaptive networks. The resulting adaptive learning rules rely on local data at the individual nodes and on collaborations among neighboring nodes in order to exploit the space-time di ...
Adaptive networks consist of a collection of nodes that interact with each other on a local level and diffuse information across the network to solve estimation and inference tasks in a distributed manner. In this work, we compare the performance of two di ...
Aims While successful termination by pacing of organized atrial tachycardias has been observed in patients, single site rapid pacing has not yet led to conclusive results for the termination of atrial fibrillation (AF). The purpose of this study was to eva ...
Embedded wireless networks find a broad spectrum of applications in transportation, environmental monitoring, logistics, supply chain management, and "pocketswitched" communication. The node mobility patterns in these applications tend to give rise to spat ...
