Now in an abridged second edition, Electrophysiological Foundations of CardiacArrhythmias focuses on teaching the fundamental concepts of cardiac cellularelectrophysiology with an emphasis on the relationship of basic mechanismsto clinical cardiac arrhythmias. Understanding this relationship and theelectrophysiological mechanisms underlying arrhythmogenesis will be invaluableto physicians entering the fields of cardiology and clinical electrophysiology, aswell as those scientists and clinicians already working in these areas.These essential concepts of electrophysiology include discussion on actionpotentials, ion channels and currents, and mechanisms of arrhythmias, andprovide the working knowledge that will enable the reader to approach a boardexam confidently. Additionally, the authors build a base of understanding that willprepare the reader for more advanced texts, such as Josephson's Clinical CardiacElectrophysiology: Techniques and Interpretations.
