Abstract :
Epicardial potential mapping (EPM) system is a main tool for cardiac electrophysiological research and clinically precise diagnosis. One of EPM´s technical difficulties is how to analyze EPM signals effectively to get pivotal information. Therefore a new united method based on dynamic iso-potential map (DIM), time-dependent correlation waveform analysis (CWA) and energy distribution were used to analyze EPM signals. The results indicated that the DIM could reflect depolarization waves´ spread visually and dynamically. Time- dependent CWA and energy distribution could reflect the depolarization waves´ spread directions and paths statistically. The concept of time-dependency made analysis focus on certain or several depolarization waves and the results were more significative. In conclusion, this united method can reflect depolarization waves´ spread law roundly and accurately. It´s fit for EPM system.
