BIOELECTRICAL INFORMATION PROCESSING——THE BODY-SURFACE HBE

<正> This paper discusses what is concerned with the technique to convert the bioelectrical signal having the s/n ratio smaller than 1 into one with the s/n ratio greater than 1 through a computerized averaging program, by describing the measurement of His bundle potential (originating in by the heart) from the body-surface for an example.In this study, not only the close correlation between the catheter and the body-surface HBE H-V intervals has been identified by various experimental methods, but the A-wave stability as well. Thus, all information as can be obtained by the catheter method, i.e. the P-A, A-H and H-V intervals and H-wave width, can also be secured by the body-surface method.
