The goal of this book is to provide an integrated overview of some intriguing problems of cardiac electrophysiology. Topics have been selected that encompass mainly aspects which have been a matter of concern and interest in our Department over the past few years. We requested from the authors not only that they provide information about their own investiga tions, but also that they integrate their results with those published by oth ers. Furthermore, we urged them to be speculative in their interpretations in order to encourage exploration of related areas of investigation. To this end, the authors have presented their ,contributions in sufficient detail so that the information may not only educate the reader but also encourage and chal lenge him. It is through the concept of total integration -from in vitro to in vivo, from animal to man, from the pure scientist to the clinician -that we hope to advance our understanding of cardiac electrophysiology. The book brings together scientific work in which important advances have been made in the seventies, and in which even more substantial pro gress is likely to be made in the present decade. The chapters have been written by investigators who are authorities in the relevant scientific field. No attempt at summarizing has been made as this may not seldom lead to oversimplification, a risk that we do not dare take. The table of contents and list of contributors are, in this regard, self-explanatory.

Electrical Phenomena in the Heart is a collection of articles that deals with cell physiology and biophysics as applicable to the heart. The book discusses the ultrastructure of heart cells, molecular arrangement of heart cell membranes, and the mechanism involved in sealing and excitation-contraction coupling. The selection describes electrophysiological studies made of embryonic heart cells to understand electrical activity, automaticity, enzyme activities, and the development of intracellular tubular systems. The text also discusses the mechanism of excitation spread between active and inactive cells. The book analyzes the structure of biological membranes and the effect of proteins on membrane potential and on the excitability process. One paper reviews the excitation process of heart cells that includes the use of a voltage clamp in cardiac preparations, as well as the role of the pacemaker. One paper examines the repolarization process involved in cardiac muscle involving the ionic composition and the kinetic properties of membrane currents, as well as the action of some drugs. The book also describes the healing process in cardiac and other muscle fibers when the heart muscle is injured. The text explains that damage to other cardiac muscle can result because of a sealing process that occurs at or near the injured site. The book also explains the model for controlling sarcoplasmic calcium concentration on a single sarcomere level in a mammalian heart. The text can prove significant to students learning heart physiology and biophysics, heart surgeons, and bio-physiologists involved in cellular research.

Progress made in the last 20 years clearly indicates that the cell surface is an extremely dynamic structure involved in fundamental processes such as cell motility, innervation, and cell adhesion. Of particular interest is the finding that, in several tissues, the cell surface is differen tiated at the intercellular region, thereby providing communicating chan nels between apposing cells. Although our actual knowledge of the precise structures and mecha in the complex process of intercellular communication is still nisms involved scanty, evidence has been presented that ions and molecules diffuse from cell to cell, establishing a physiological continuum. Embryonic differentia tion, cell growth, neoplasia, electrical synchronization in nerve and mus cles, as well as immune response seem to be related to ceIl communication. In organizing this volume, it has been our intention to provide the reader with an actual review of the processes involved in intercellular communication in normal tissues as well as in neoplasia. We sincerely believe that the opinions and experiences described herein will be of help in establishing new perspectives for the future of this exciting new field of cell biology. We wish to thank all the colleagues who joined us in the organization of this volume, as well as Plenum Publishing Corporation for making its appearance possible.

In the denervated state the mammalian heart, both in vivo and in vitro, is excited at very regular intervals, the coefficient of variance of the interbeat intervals not exceeding 2%. The pacemaker that is the source of this regular ex citation is localised normally within the sinus node (" sino-atrial node " node of Keith and Flack), a most intriguing small piece of tissue in the caval corner of the right atrium. A small portion of this node containing a group of probably only a few thousands of cells fires spontaneously, that means without any exter nal influence to trigger their activity. The so called pacemaker cells do this by letting their membrane potential fall to the level where an action potential will start which subsequently activates surrounding cells to fire an action po tential. The first question which is tackled in this book is which processes underly this spontaneous diastolic depolarization. This is discussed in section I, concerning the fundamental properties of pacemaker cells with special refer ence to ionic membrane currents. Although views still quite differ about the exact nature of the membrane processes that cause the automatic pacemaker dis charge there is agreement that diastolic depolarization is brought about by the interaction of a number of ionic current systems, including both inward and out ward going currents.

Hearts and Heart-Like Organs, Volume 1: Comparative Anatomy and Development focuses on the complexities of the heart and heart-like organs in various species, from the invertebrates and the lower vertebrates to humans. More specifically, it investigates the hearts of worms and mollusks, urochordates and cephalochordates, fishes, amphibians, reptiles, birds, mammals, and humans. Organized into 11 chapters, this volume begins with an overview of myogenic hearts and their origin, the circulatory system of the annelids, and the nervous control and pharmacology of mollusk hearts. It then discusses the phyletic relationships and circulation systems of primitive chordates, cardiovascular function in the lower vertebrates, fine structure of the heart and heart-like organs in cyclostomes, and fine structure as well as impulse propagation and ultrastructure of lymph hearts in amphibians and reptiles. It also explains the neural control of the avian heart, functional and nonfunctional determinants of mammalian cardiac anatomy, postnatal development of the heart, and anatomy of the mammalian heart. The book concludes with a chapter on the anatomy of the human pericardium and heart. This book is a valuable resource for biological and biomedical researchers concerned with the anatomy and physiology of the heart.

For the clinician the sinus node is more or less a hidden structure and only by indirect assessment he is able to say something about the function of this center of pacemaker activity. The morphologist, however, is able to describe the structural microscopic and even electronmicroscopic features of this structure. The only disadvantage is that, as soon as he is coming into the picture, the tissue is dead. The physiologist tries to investigate the electrophysiological behavior of the sinus node. Since there is not a human being willing to give his sinus node for research, he has to do his investigation on isolated preparations of animals. Though there are a lot of experts in the field of the sinus node they nearly never speak the same 'language'. Therefore, it was my dream to bring all those people - or at least some of them -together on a workshop. I had the feeling that it was important to organize such a meeting without an audience but only with 'experts'.
