RECENT DEVELOPMENTS IN MEASURING TECHNIQUES AND DIAGNOSTIC INTERPRETATION OF THE HEARTS ELECTRIC-FIELD (REVIEW)

This is a brief review of the reports at the 21st International Congre ss on Electrocardiology (June 3-7, Yokohama, Japan) at which topics bo th experimental and theoretical concerning the measurement and interpr etation of the electric potentials of the heart and related problems w ere discussed. Beside the numerous reports concerning clinical studies of the electric changes in both normal and diseased hearts, some crit ical reviews were presented. Recent results concerning the subtle mech anisms of the genesis of the extracellular cardiac electric field were reported, and assessments were made of noninvasive methods for detect ing electrophysiological. functions and the states of the heart and th eir clinical applications.
