Book Description
Kohl (Cardio Mechano-Electric Feedback Lab, Oxford University) documents the role of mechano-electric feedback (MEF) in electrical and mechanical pathological remodeling of cardiac function. Sections cover sub-cellular mechanisms of cardiac MEF, effects of MEF on cardiac cellular electrophysiology, experimental manifestations of MEF in the heart, cardiac MEF in normal physiology, cardiac MEF as a pathogenic mechanism, MEF as a mechanism involved in therapeutic interventions, and the outlook for the future. B&w and color photos and medical images are included. Annotation: 2005 Book News, Inc., Portland, OR (booknews.com).

Book Description
The effective management of cardiac arrhythmias, either of atrial or of ventricular origin, remains a major challenge. Sudden cardiac death due to ventricular tachyarrhythmias remains the leading cause of death in industrialized countries while atrial fibrillation is the most common rhythm disorder; an arrhythmia that’s prevalence is increasing and accounts for nearly one quarter of ischemic stokes the elderly population. Yet, despite the enormity of the problem, effective therapeutic interventions remain elusive. In fact, several initially promising antiarrhythmic agents were found to increase rather than decrease mortality in patients recovering from myocardial infarction. The question then is what went wrong, why have these interventions proven to be so ineffective? An obvious answer is the drugs were designed to attack the wrong therapeutic target. Clearly, targeting single ion channels (using either isolated ion channels or single myocytes preparations) has proven to be less than effective. What then is the appropriate target? It is well established that cardiac electrical properties can vary substantially between single cells and intact preparations. One obvious example is the observation that action potential duration is much longer in isolated cells as compared to multi-cellular preparations or intact hearts. Due to the low electrical resistance between adjacent myocytes, the cells act in coordinated fashion producing “electrotonic interdependence” between neighboring cells. Myocardial infarction and/or acute ischemia provoke profound changes in the passive electrical properties of cardiac muscle. In particular, electrotonic uncoupling of the myocytes disrupts the coordinated activation and repolarization of cardiac tissue. The resulting compensatory changes in ionic currents decrease cardiac electrical stability increasing the risk for life-threatening changes in the cardiac rhythm. Thus, the electrical properties of myocardial cells must be considered as a unit rather than in isolation. It is the purpose of this Research Topic to evaluate the largely neglected relationship between changes in passive electrical properties of cardiac muscle and arrhythmia formation.

Book Description
This book presents the latest findings in the field of cardiac mechanobiology in health and disease. Cardiac mechanobiology provides knowledge of all aspects of mechanobiology of the heart. Cardiomyogenesis is discussed as well as the mechanobiology of cardiac remodeling and regeneration. The molecular mechanisms of mechanoperception and mechanotransduction in cardiomyocytes are explained, as well as stretch induced differentiation of cardiomyocytes derived from induced pluripotent stem cells. This volume of the series Cardiac and Vascular Biology complements the volume Vascular Mechanobiology in Physiology and Disease (volume 8) published in this series. The book is aimed at clinicians as well as researchers in cardiovascular biology, bioengineering and biophysics, and also represents an educational resource for young researchers and students in these fields.

Book Description
The increasing pace of advances in cardiology throughout the last few decades has fundamentally altered the natural course of heart patients. In the last few years, available therapies have been revolutionized completely by new transcatheter therapeutic approaches, novel ventricular assist devices, and new drugs. Also, molecular biology and genetics have a rapidly growing impact on cardiovascular diseases, enabling the field of regenerative medicine to become increasingly closer to routine clinical implementation. Emerging Technologies for Heart Diseases was conceived to cover the recent extensive literature on current and novel therapeutic options for cardiac patients. The first volume is dedicated to heart failure and valvular disorders, and the second covers myocardial ischemia and arrhythmias. The clinical topic is addressed in several chapters divided according to the therapeutic approach (mechanical or electrical device-based, or cell and gene-based). Each of the 46 chapters focuses on clinically available solutions, new therapies currently under evaluation in clinical trials, promising preclinical technologies, and emerging concepts and innovations that have not yet been tested in a preclinical model. Also, the book discusses future challenges and opportunities for clinical implementation. Lessons learned from abandoned experimental practices are also covered, giving the readers the widest possible perspective of current therapeutic dilemmas. Overall, this textbook was designed for physicians who want to stay up-to-date with current therapies and those of the future, for biomedical companies, and for those who wish to broaden their knowledge of new cardiovascular therapeutic options. Provides a comprehensive review of the latest therapeutic developments for heart failure, valvular disorders, myocardial ischemia and arrhythmias, and their clinical implications Written by both specialists in the field and established researchers, it delivers a review of emerging medical technologies and presents insight into their therapeutic promise Chapters are arranged according to disease pathogeneses and relevance and include coverage of the mechanical, electrophysiological, and biological approaches for the management of patients with myocardial ischemia and arrhythmias

Book Description
This completely updated and expanded 2nd Edition provides all the information needed in order to understand the complex molecular, cellular and genetic mechanisms that underlie normal and abnormal cardiac rhythms. Its goal is to help physiologists and clinicians alike develop better preventive and treatment strategies. The respective chapters cover a broad range of topics, including the role of specific ion channels and transporters, gap junctions, intracellular Ca2+ handling in pacemaker activity, impulse conduction, and the activity of atrial and ventricular myocardium. Special emphasis is placed on the unique electrophysiology of specialized pacemaking cells and conducting fibers. In turn, several types of inherited and acquired ventricular arrhythmias are presented in detail. Clinicians will especially appreciate the updated information on even common disorders like atrial fibrillation and their impacts on human physiology. In closing, the book goes “one step further” and considers future prospects, e.g. novel antiarrhythmic agents and new concepts like optogenetics, in the context of heart rate regulation. Accordingly, it offers readers a solid reference guide to everything they need to know about human heart rate and rhythm.
