Thoroughly revised and updated, this Fourth Edition is the only current book that integrates cellular and subcellular elements of cardiovascular physiology in the analysis of physiologic and pathophysiologic responses. In straightforward terms, with more than 600 diagrams and illustrations, the book explains the key principles crucial to understanding how the cardiovascular system and its components function and malfunction.

For this edition, Dr. Opie has enlisted eight internationally eminent co-authors and added a new chapter on cell signaling. The chapters on physiology of the ECG and arrhythmias contain many more ECGs. More than half of the illustrations—including 12 color plates—are new.
