In this monograph, Dr. Kossmann and five of his co-workers present a review of advances in electrocardiography during the past decade, including previous and recent contributions of their own. Its background is a series of postgraduate courses in fundamentals of electrocardiography, and its aim is to narrow some of the gaps between progress made in various electrophysiologic laboratories and the needs of clinical electrocardiography.
The subject is presented under four principal categories. The first, dealing with present knowledge of the source of electrical potential, consists of chapters on the transmembrane potential, its ionic basis, and its experimental modifications, including electrical alternans and its relation to myocardial mechanics. Five subsequent chapters are devoted to the conducting medium, the dipole theory, the movement of the theoretical heart center, and the bearing of all these factors on the validity of various lead systems used in experimental and empirical electrocardiography and vectorcardiography.
