Problems related to the selection of suitable electrocardiographic leads and the preparation of the electrocardiographic data for automatic processing have been discussed elsewhere (1, 2). Three corrected orthogonal leads [Frank's Lead System (3)] are recorded on magnetic analog tape using FM channels. Since it had been shown previously (4) that orthogonal leads contain the same clinical information which is used in the analysis of conventional 12-lead records, the application...References1.
