Abstract
A body surface potential mapping system equipped with a microprocessor has been developed.
The system enables high speed, real time and simultaneous observation of ECG data of 96 lead points in a character display mode. The machine has functions not only of making such various basic data processing as base line correction or linear interpolation for malfunctioned electrodes, but also of generating isopotential contour map, to record data onto floppy disk, to make hard copies of displayed patterns and characters, and so on. To increase the operation speed, all the assembler programs were put in a module. Thus, an operator can easily recognize the spatial motion pattern of the body surface potential map and in addition, find out malfunctioned channels by observing the pattern. Also a belt type electrode system allows quick and flexibly adaptable attachment.
The system has proved its practical usefulness under cooperation of cardiologists; over 100. patients with cardiac diseases have been recorded.
The system has a peculiar function to transmit the data to the other large computer center to make further high level data processing like inverse estimation of epicardial potentials.
