Available in PDF, EPUB and Kindle. Book excerpt: Cardiac Dynamics is the name of a relatively young field of study, born from the fruitful interaction between branches of two different disciplines: medicine and physics. "Dynamics" is the branch of physics which deals with the action of forces on bodies or particles in motion or at rest. "Cardiac" relates to the clinical field of cardiology but also to cardiophysiology, both of which are specialized branches of medicine. Narrower than the well established field of Hemodynamics, Cardiac Dynamics is restricted to dynamic phenomena occurring in and around the heart. The mathematical treatment of such phenomena, however, is vastly more complex because of the intricate nature of the mechanisms involved in the cardiac action. Thus, whereas hemodynamics is concerned with predominantly passive (visco-) elastic structures - vessels - containing time-variant flow of viscous flui- blood -, the mechanical study of the heart requires additional con siderations such as: active elastic components representing the contractile mechanism of cardiac muscle, complex geometry and fiber structure in the myocardial wall, autoregulatory mechanisms, and intricate flow patterns associated with valve motion. Viewed in this light it is not surprising that attempts to describe ventricular pump function and to quantify contractile performance have not reached the level of sophistication which is common in e. g. arterial hemodynamics. For the same reason, many of the often simplified approaches to describe ventricular mechanics failed to stand up to more rigorous theoretical, experimental or clinical testing.

Book excerpt: This ambitious and comprehensive handbook represents an essential contribution to our current understanding of interactions between heart and brain, a research topic generating growing interest. Despite the increasing awareness that neural mechanisms are the primary cause of cardiac disease and its progression, therapy continues to focus on end-organ protection and does not approach the neural core of the problem. Growing public health problems such as heart failure are still treated with autonomic drugs that are 30-40 years old and simply act on cardiac receptors. However, it has now been shown that the progression of ischemic heart disease to heart failure is mainly due to abnormal central responses to incipient cardiac disease, with neural activation the primary cause rather than the consequence of cardiac remodeling. Written by leading international experts in their respective research areas, the book presents a variety of perspectives on the core topic: from social and philosophical to gender-related aspects. It is designed for a broad readership and includes dedicated sections for cardiologists, psychiatrists, neurologists and psychotherapists looking for a more insightful and targeted approach to neuro-cardiovascular disease.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years there has been a growth in interest in studying the heart from the perspective of the physical sciences: mechanics, fluid flow, electromechanics. This volume is the result of a workshop held in July 1989 at the Institute for Nonlinear Sciences at the University of California at San Diego that brought together scientists and clinicians with graduate students and postdoctoral fellows who shared an interest in the heart. The chapters were prepared by the invited speakers as didactic reviews of their subjects but also include the structure, mechanical properties, and function of the heart and the myocardium, electrical activity of the heart and myocardium, and mathematical models of heart function.
Download or read book Complex Structure and Dynamics of the Heart written by Philip Bittihn and published by Springer. This book was released on 2014-12-27 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: This award-winning thesis investigates the mechanisms underlying cardiac arrhythmia development and termination from an entirely new perspective. By viewing the heart as a complex system, the author uses theoretical tools from nonlinear dynamics combined with numerical simulations and experiments to achieve insights into the relationship between its structure and dynamics, thereby paving the way towards innovative low-energy defibrillation strategies. The work tackles, among other things: the effect of substrate heterogeneity on the spatial-temporal dynamics of cardiac arrhythmias and ways in which weak pulsed electric fields can be used to control these dynamics in heterogeneous cardiac tissue. The long-term vision of this research is to replace the current strategy of applying painful and sometimes tissue damaging electric shock – currently the only reliable way to terminate life-threatening fibrillation – by a more subtle but equally effective intervention. The book maps out a number of promising research directions for biophysicists and medical researchers working on the origins and treatment of cardiac arrhythmias.

Available in PDF, EPUB and Kindle. Book excerpt: 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 was released on 2012-12-06 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cardiovascular dynamics is a field in which modelling and systems analysis have formed an extremely important discipline. For example, understanding of even such a fundamental function of the circulation as the relationship between central venous pressure apd cardiac output has required evolution of a pertinent model based on years of exhaustive ex perimental investigations by Starling, Starr, and Guyton. Hemodynamic analyses of pulsatile pressures and flows in the arteries and veins have been a continuing challenge taken up by champions of fluid dynamics such as Frank, Wetterer, Taylor, and Wormersley, just to mention a few names, and some kind of model was always proposed as a conceptual framework. An even greater challenge to cardiovascular dynamicists was how to analyze the intermittent coupling of the ventricle and the arterial or venous vasculature through the valve. The availability of numerical solutions by computer and the recently evolved ventricular model with a time-varying elastance and a pressure-dependent internal resistance opened the way to analysis of this coupling. The ever increasing speed of computers has also facilitated trips between the fre quency and the time domain, even on-line for some experimental studies. This book contains many analyses dedicated to the interactions between the heart and the vasculature, providing the reader with findings at the cutting edge of current research in this field.

It then explores more advanced topics for a physics-based understanding of phenomena effectively encountered in clinical cardiology. It stands as an ideal learning resource for physicists and engineers working in cardiovascular fluid dynamics, industry engineers working on biomedical/cardiovascular technology, and students in bio-fluid dynamics. Written with a concise style, this textbook is accessible to a broad readership, including students, physical scientists and engineers, offering an entry point into this multi-disciplinary field. It includes key concepts exemplified by illustrations using cutting-edge imaging, references to modelling and measurement technologies, and includes unique original insights.
