The methodology of clinical analysis of electric heart field.

A brief description of the methodology of analysis of the electric heart field using electrocardiograms, vectorcardiograms, diagrams of potential maxima/minima and body surface potential maps is presented. The text is focused on the description of different kinds of isopotential and isointegral maps and their diagnostic possibilities. A detailed description of the diagram of potential maxima/minima and its place in diagnostic of different disturbances of the heart muscle and conduction defects is given.
