The Poincare plot (named after Henri Poincare) is a popular two-dimensional visualization tool for dynamic systems due to its intuitive display of the dynamic properties of a system from a time series. This book presents the basis of Poincare plot and focus especially on traditional and new methods for analysing the geometry, temporal and spatial dynamics disclosed by the Poincare plot to evaluate heart rate variability (HRV). Mathematical descriptors of Poincare plot have been developed to quantify the autonomic nervous system activity (sympathetic and parasympathetic modulation of heart rate). Poincare plot analysis has also been used in various clinical diagnostic settings like diabetes, chronic heart failure, chronic renal failure and sleep apnea syndrome. The primary aims of quantification of the Poincare plots are to discriminate healthy physiological systems from pathological conditions and to classify the stage of a disease. The HRV analysis by Poincare plot has opened up ample opportunities for important clinical and research applications. Therefore, the present book can be used either for self-study, as a supplement to courses in linear and nonlinear systems, or as a modern monograph by researchers in this field of HRV analysis.

Die medizinische Behandlung der ungewollten Kinderlosigkeit wird hierzulande nach wie vor mit einer Mischung aus Interesse am medizinisch-technischen Fortschritt und Sorge uber die mogli- cherweise nicht mehr kalkulierbaren Risiken dieses Fortschrittes betrachtet. Die Reaktionen reichen dabei von der implizi ten Gleichsetzung konkreter Formen der Reproduktionsmedizin mit den fiktiven Verhaltnissen in der 'Schonen Neuen welt'1, bis hin zu Einschatzungen, wonach sich die Reproduktionsmedizin in naher Zukunft als ein unverzichtbares Instrument bei der Bekampfung eines langandauernden Bevolkerungsruckganges in der BRD erweisen 2 werde. Auch wenn sich in den letzten 5-10 Jahren das Interesse der Offentlichkeit verstarkt den verschiedenen Formen der medizini- 3 schen Behandlung ungewollter Kinderlosigkeit zugewandt hat, so scheint mit diesem verstarkten Interesse kein Anstieg der Anzahl Der Vergleich des heutigen Potentials der Reproduk- tionsmedizin mit den Schilderungen der industriellen Erzeugung von Menschen in A. Huxleys Roman "Schone Neue Welt" gehort zu den Standardbildern in weiten Teilen der Literatur uber die medizinische Behandlung der ungewollten Kinderlosigkeit. So z.B. auch bei: Hirsch, G. und Eberbach W. (1987): Auf dem Weg zum kunstlichen Leben - Retortenkinder, Leihmutter, pro- grammierte Gene Basel, Boston, Stuttgart. S.31ff. 2 So ein Reproduktionsmediziner in der Fernsehsendung 'Explosiv' (RTL 22.5.'91). 3 Man denke z. B. nur an die Kontroversen im Zuge der Erarbeitung des Embryonenschutzgesetzes, an die Richt- linien zur Durchfuhrung der In-vitro-Fertilisation der Bundesarztekammer, an die Initiativen auf dem 56.

Arthroscopic surgery has been one of the biggest Orthopedic advances in the last century. It affects people of all ages. Total joint replacement may capture popular imagination, but arthroscopy continues to have a greater effect on more people. This Atlas provides the most up to date resource of advanced arthroscopic techniques, as well as including all the standard procedures. Beautifully illustrated and supported by online videos of the latest techniques, this Atlas will appeal to both experienced shoulder surgeons as well as the orthopedic surgeon seeking to enhance his or her knowledge of shoulder arthroscopy.
