The objective of this study is to find early signs of sustained VT-VF in patients with an implanted cardioverter-defibrillator (ICD). These devices are able to safeguard patients by returning their hearts to a normal rhythm via strong defibrillatory shocks; additionally, they store the 1000 beat-to-beat intervals immediately before the onset of a life-threatening arrhythmia. We study these 1000 beat-to-beat intervals of 17 chronic heart failure ICD patients before the onset of a life-threatening arrhythmia and at a control time, i.e., without a VT-VF event. To characterize these rather short data sets, we calculate heart rate variability parameters from the time and frequency domain, from symbolic dynamics as well as the finite-time growth rates. We find that neither the time nor the frequency domain parameters show significant differences between the VT-VF and the control time series. However, two parameters from symbolic dynamics as well as the finite-time growth rates discriminate significantly both groups. These findings could be of importance in algorithms for next generation ICD's to improve the diagnostics and therapy of VT-VF.}, language = {en} } @article{KuznetsovNeumannPikovskijetal.2000, author = {Kuznetsov, Sergey P. and Neumann, Eireen and Pikovskij, Arkadij and Sataev, I.

The hypothesis of universality, based on renormalization group arguments, is advanced to explain the observed scaling properties for the critical attractor and for the parameter plane arrangement in the neighborhood of the criticality.}, language = {en} } @article{BeckerGetzin2000, author = {Becker, Thorsten and Getzin, Stephan}, title = {The fairy circles of Kaokoland (North-West-Namibia) : origin, distribution, and characteristics}, year = {2000}, language = {en} } @article{KatzorkePikovskij2000, author = {Katzorke, Ines and Pikovskij, Arkadij}, title = {Chaos and complexity in a simple model of production dynamics}, issn = {1026-0226}, year = {2000}, language = {en} } @article{PietschDarowskiUlyanenkovetal.2000, author = {Pietsch, Ullrich and Darowski, Nora and Ulyanenkov, A. and Grenzer, J{\"o}rg and Wang, K.
