The first edition of the book was written employing mathematical techniques to formulate the physical principles involved in the structural and functional correlates of the underlying physiology.This current and self-contained second edition updates many of the new findings since its first edition a decade ago. It also includes a new chapter on the 'Interaction with the Heart'. The dynamics of the arterial system, the venous system, the microcirculation and their interaction with the heart are quantitatively described in terms of their structures and functions. Clinical measurements, applications to the cardiovascular field and physiological mechanisms are clearly identified throughout the text. Most importantly, worked examples are provided, such that the readers can appreciate the application aspects of the underlying formulation.

Circulatory System Dynamics reviews cardiovascular dynamics from the analytical viewpoint and indicates ways in which the accumulated knowledge can be expanded and applied to further enhance understanding of the normal mammalian circulation, to ascertain the nature of difficulties associated with disease, and to test the effect of treatment. Comprised of 10 chapters, this volume begins with an overview of the circulatory system, including its anatomy and the trigger for myocardial (heart muscle) contraction. The discussion then turns to measurement of blood pressure using invasive and non-invasive techniques; blood flow measurement, with emphasis on cardiac output and measurement in the microcirculation; the system and pulmonary arterial trees; and pulsatile pressure and flow in pulmonary veins. Subsequent chapters explore microcirculation and the anatomy of the microvasculature; the heart and coronary circulation, paying particular attention to the Frank-Starling mechanism and indices of myocardial "contractility"; and control of blood pressure, peripheral resistance, and cerebral flow. The last two chapters deal with circulatory assistance and the closed cardiovascular system. This book will be of interest to students, practitioners, and researchers in fields ranging from physiology and biology to biochemistry and biophysics.

This book summarizes the papers presented at the symposium "Dynamics and Regulation of the Arterial System" held at Erlangen on 28-30 October 1977 in honor of Professor Erik Wetterer. The aim of the symposium was an inten sive exchange of ideas within a mUltidisciplinary group of scientists who are specialists in their fields of research. It is obvious that a two-day symposium covering such a wide range of topics could only highlight certain aspects of the latest research on the cardiovascular system. The book is divided into three sections. The first part deals with arterial hemo dynamics. Emphasized are the mechanical properties of the arterial wall, in particular the smooth muscle, fundamental parameters for the description of pulse wave propagation, such as attenuation, phase velocity, and reflection of pulse waves. Furthermore, new methods for recording arterial diameters and the latest results in determining pulsatile pressure and pulsatile diameter of arteries in vivo as well as from calculations based on models of the arterial system are presented. The second part deals with applications of the control theory and the principles of optimality of the cardiovascular system in toto and of single regions of this system. Contributions to research in the field of regulation of blood volume and of regional hemodynamics are also presented. The third part covers problems of interaction of the heart and the arterial system, including fluid mechanics of the aortic valves and the coronary blood flow under normal and pathologic conditions.

The ultrasound velocity tomography allows measurement of cardiac geometries for various phases in the cardiac cycle. The present tomograph makes reconstruc tions at intervals of 20 ms. Because of a lack of clear (intramural) landmarks (except the roots of the papillairy muscle), it is difficult to pinpoint spatial trajectories of particular points in the heart. Therefore, a second method was developed of injecting radiopaque markers in the heart and following their motion patterns during the cardiac cycle with help of a biplane X-ray equipment. The data obtained with both methods can be implemented in our finite element model of the heart to compute intramural stresses and strains. The results obtained sofar with the extended Darcy equation to account for the interaction of blood rheology and tissue mechanics look promising. Further testing with more sophisticated subjects than mentioned in Figure 9 is required before it will be implemented in our finite element model of the heart. We conclude that analysis of regional cardiac function, including regional myocardial blood flow, requires still a major research effort but the results obtained sofar justify, to our opinion, a continuation in this direction. Acknowledgement The authors acknowledge Dr. C. Borst and coworkers for doing the animal experiments and prof. Van Campen and dr. Grootenboer for their participation is some aspects of this work.
