Abstract:
If heart function is normal, the atrial cel s are excited in a stable rhythm. But this would change during atrial fibril ation. In this paper, after comparing with the method of characteristic point, we use the dominant frequency method to analyze the activation pattern under sinus and atrial fibril ation rhythm in different parts of atria based on epicardial mapping system. It is found that the activation rhythm changes a lot in different parts of atria, and the automaticity of atrial cel s change obviously in somewhere. The result shows that dominant frequency method is very suitable for the analysis of atrial fibril ation signal. What's more, we also roughly discuss the role of this method in exploring the driving sources during atrial fibril ation.
