| Abstract: | Epicardial mapping is a method of observing, detecting and analyzing cardiac eleetropotential signals with precision. Doctors can clearly acquire information of blood - supply in the isehemia myoeardium through real - time potential map or activation map during the bridging operation of coronary artery. In this paper, We describe the hardware platform which is composed of electrodes, 64 - channel synchronous amplifier, PCI data -sampling card, computer etc. Our software system consists of filter, interpolation, abstraction of characteristic points, colorful equipotential diagram and isochronograph etc. |
