Electrophysiological foundations of cardiac arrhythmias : a bridge between basic mechanisms and clinical electrophysiology [E-Book]

Now in an abridged second edition, Electrophysiological Foundations of Cardiac Arrhythmias focuses on teaching the fundamental concepts of cardiac cellular electrophysiology with an emphasis on the relationship of basic mechanisms to clinical cardiac arrhythmias. Understanding this relationship and the electrophysiological mechanisms underlying arrhythmogenesis will be invaluable to physicians entering the fields of cardiology and clinical electrophysiology, as well as those scientists and clinicians already working in these areas. These essential concepts of electrophysiology include discussion on action potentials, ion channels and currents, and mechanisms of arrhythmias, and provide the working knowledge that will enable the reader to approach a board exam confidently. Additionally, the authors build a base of understanding that will prepare the reader for more advanced texts, such as Josephson's Clinical Cardiac Electrophysiology: Techniques and Interpretations.
