Produktbeschreibung

The past years have witnessed considerable progress in the field of fundamental research in cardiology. Nevertheless, numerous problems and controversial concepts remain. Some of these controversies concern relatively simple issues, e. g. the question of the extent to which a common length-tension or pressure-volume relationship exists independent of type of contraction and preload. The present volume is a compendium of an Erwin Riesch sympo sium held July 12-13,1985, with the aim of critically analysing generally accepted concepts and theories as well as current trends in cardiology. In common with previous Erwin Riesch symposia, priority was given to issues concerning chronic reactions of the heart, although basic principles of normal myocardial contraction and ventricular dynamics as well as clinical aspects were also discussed. We are greatly indebted to the Erwin Riesch-Stiftung for the invaluable generosity which enabled us to hold the symposium. R.Jacob VII Contents Foreword ................................ . V I.
