Pathological heart rhythms are a major health issue. In this book
experts from various fields provide an important context for
understanding the complicated molecular and cellular mechanisms that
underlie normal and pathophysiological cardiac rhythms.
Individual chapters cover a full range of topics, including the ionic
basis of pacemaking, the role of specific channels and transporters in
sinoatrial node pacemaking, altered intracellular Ca2+
handling in response to disease, computer modeling of the action
potentials of pacemaker and working cardiomyocytes, genetic and
molecular basis of inherited arrhythmias and a review of established and
novel antiarrhythmic agents. Due to the key importance of the
specialized pacemaker cells and tissue (sinoatrial and atrioventricular
nodes) in maintaining heart rate and rhythm, special emphasis is placed
on the peculiar electrophysiology of these cells.
