Problems and Trends in Body Surface Mapping of Bioelectric Fields
Bioelectric phenomena are generally studied by recording and displaying local potential changes as a function of time. Electrocardiography and electroencephalography are typical examples of this approach. On the other hand, a great deal of information on the topography and time-course of electrophysiological events in the heart, skeletal muscle and the nervous system has been recently obtained by another method, i.e. by mapping the instantaneous distribution of bioelectric potentials in two or three dimensions.
