Abstract

This book was designed for the beginning student in electrocardiography. Its purpose is to clarify the basic principles involved in the study of electrocardiograms and their clinical interpretation. The author has done a commendable job in explaining the physiology and electrophysics in both normal and abnormal electrocardiograms by liberal use of schematic illustrations. After establishing the foundation of the electrical phenomena of electrocardiography, their clinical application is discussed.
