This book presents new aspects on electrophysiological mechanisms and catecholaminergic contributions in the setting of acute and chronic myocardial ischemia. Special emphasis is placed on the full scope from basic molecular and cellular mechanisms to experimental models of close clinical proximity. A number of internationally distinguished scientists present their latest findings in this significant research area within the perimeter of cardiovascular disease which continues to lead mortality statistics in most industrialized countries. Contents of this book cover, in addition to other subjects, release and uptake of catecholamines in ischemia, regulation of receptors, adrenergic contribution to ventricular arrhythmias and mechanisms of ischemic malignant arrhythmias as well as underlying changes in membrane currents and the electrophysiological response to beta-adrenergic blocking drugs. In addition to original contributions, a number of editorial chapters are included for conclusions and future development in these areas.
