A Visual Expression to Show Epicardial Electrical Activity Comprehensively

This paper refers to a new design to show epicardial electrical activity visually and comprehensively. With emulation modeling technology and linear interpolation, electrical activity on the epicardial surface can be displayed directly, precisely and continuously. Simulation tests and animal tests proved that the system could describe the cardiac activation vividly, just like weather nephogram. The proposed method may make this epicardial mapping system an important tool in studying cardiac electrophysiology.
