This unique book is entirely written by these two authors, who have spent a lifetime investigating and defining the electrophysiological mechanisms causing cardiac arrhythmias. Both authors have received numerous awards for their teaching of this subject to students at all levels, from medical students to clinical electrophysiologists. They use their well-recognized teaching ability to clearly elucidate how basic electrophysiological properties and mechanisms cause clinical arrhythmias. The book explains how features of electrocardiograms of the different arrhythmias and the response of arrhythmias to electrophysiological testing can be explained by electrical properties of cardiac cells. It clearly unravels the intricacies of the relationship of cellular electrophysiology to clinical arrhythmias.
